Rinsing with sage tea will not cure gum disease. It may calm a sore, puffy gum for a few days while you deal with the cause — and that gap between “cures it” and “takes the edge off” is where most advice about herbs for teeth and gums falls apart.
Here is the short version. A handful of plant rinses have real, if modest, support: they reduce plaque and gum inflammation about as well as a chlorhexidine rinse over two to four weeks, in trials that were mostly small and short (Canadian Journal of Dental Hygiene umbrella review, 2024). Clove has a numbing effect that held up against a pharmacy anesthetic in a real trial. Nothing here regrows bone, reverses periodontitis, or drains an abscess. Herbs are the thing you add on top of brushing, cleaning between your teeth, and seeing a dentist — not the thing you use instead.
First, the boring part that actually protects your teeth
Gum disease is a bacterial infection of the tissue holding your teeth in place. It starts as gingivitis — red, swollen gums that bleed easily — and if it progresses to periodontitis, the gums pull away from the teeth, pockets form, and the bone underneath starts to go (NIDCR gum disease overview). About 42% of US adults aged 30 and older have periodontitis, and roughly 8% have the severe form (CDC gum disease facts, 2024).
Gingivitis is reversible with daily brushing, flossing, and professional cleanings (MedlinePlus on gum disease). Periodontitis is not something you rinse away. Smoking is the single biggest risk factor you can change (NIDCR).
A herbal rinse sits on top of that foundation. It does not replace any part of it.
What the research on herbal rinses actually shows
An umbrella review published in 2024 pooled the existing systematic reviews on herbal mouthrinses and toothpastes. Its conclusion was measured: some herbal products, particularly mouthrinses, have “a similar level of positive effect on plaque and gingivitis reduction” and may work as adjuncts to conventional products. The authors then flagged the catch — nearly every trial ran under four weeks, and publication bias was a concern (Mehta et al., *Canadian Journal of Dental Hygiene*, 2024).
A separate review of seven trials landed in the same place: herbal and non-herbal rinses both reduced plaque and gingival scores, five of the seven found no meaningful difference between them, and “the evidence is based on low-quality trials” (Singi, *Cureus*, 2022).
Read that as encouraging rather than conclusive. Short trials in small groups tell you a rinse is plausible. They do not tell you what happens to your gums over a year.
For comparison, the American Dental Association recognizes chlorhexidine, essential oils, and cetylpyridinium chloride as antimicrobial rinse ingredients shown to reduce plaque and gingivitis, and fluoride for preventing decay (ADA on mouthrinses, 2026). Chlorhexidine and CPC can stain teeth and restorations brown, which is one honest reason people look for alternatives.
The best herbs for teeth and gums, ranked by evidence
Clove, for short-term tooth pain
Clove is the one herb in this category with a genuinely persuasive human trial. Researchers applied homemade clove gel, 20% benzocaine gel, or matching placebos to the gums of 73 adult volunteers, then stuck them with a needle. Both clove and benzocaine produced significantly lower pain scores than placebo (p=0.005), with no meaningful difference between the two (Alqareer et al., *Journal of Dentistry*, 2006).
That is a numbing effect measured over minutes, not a treatment. A tooth that hurts enough to need clove oil has a problem clove oil cannot fix.
Use whole cloves or a heavily diluted oil, and keep it off healthy tissue. Undiluted clove oil concentrate is corrosive to the lining of the mouth: one published case describes a woman whose canker sores turned into widespread ulcers, peeling lips, and brown crusting after she applied clove oil concentrate for two days (*Medali*, 2022). Swallowed clove oil is worse — 10 to 30 mL has caused coma and acute liver failure, mostly in infants who got into a bottle (LiverTox: Eugenol). More on what cloves are and aren’t good for.
Aloe vera, for inflamed gums
The best-studied herbal rinse for gingivitis. A systematic review of six randomized trials covering 1,358 people found aloe vera reduced plaque and gum inflammation, performing comparably to chlorhexidine for inflammation but less well for plaque control — with fewer side effects (Al-Maweri et al., *International Journal of Dental Hygiene*, 2020).
If your gums are irritated and chlorhexidine’s staining bothers you, this is a reasonable thing to raise with your dentist.
Green tea
A randomized trial in 60 children aged 10 to 14 compared a green tea rinse, a green tea plus ginger rinse, and chlorhexidine over 30 days. All three cut plaque and gingival scores significantly from baseline, and the herbal rinses held up against chlorhexidine as an adjunct to brushing (*Journal of Indian Society of Periodontology*, 2021).
Sixty children over one month is a small, short study. It is a reason to try cooled green tea as a rinse, not a reason to expect much.
Turmeric
Six randomized trials totaling 320 people found curcumin mouthwash statistically indistinguishable from chlorhexidine for both plaque index and gingival index (Al-Maweri et al., *International Journal of Dental Hygiene*, 2021). Five of those six trials carried a high risk of bias, which is why the appraisal in the National Elf Service called for “high quality well reported studies of appropriate size and duration” before anyone treats this as settled (National Elf Service, 2021).
Turmeric stains. Expect yellow on your toothbrush and, temporarily, your tongue.
Guava leaf
Sixty adults with moderate-to-severe chronic gingivitis were randomized to a 0.15% guava leaf extract rinse, 0.2% chlorhexidine, or plain water after a professional cleaning, then followed for three months. Guava and chlorhexidine both beat the placebo on gingival and plaque scores, with significant drops in bacterial counts (Nayak et al., *BMC Complementary and Alternative Medicine*, 2019). Three months is longer than most trials in this field, which makes it more useful than its size suggests. More on the guava tree’s leaves and bark and how they are traditionally prepared.
Chamomile and licorice, for mouth ulcers
Different job. If your problem is a canker sore rather than bleeding gums, these two are the better bet.
The EU herbal monograph lists chamomile flower as a traditional treatment for “minor ulcers and inflammations of the mouth and throat,” at 1–5 g of flowers per 100 mL of water for rinsing, used for no more than a week without checking in (European Medicines Agency, 2015). This is a European traditional-use registration, not a US claim, and traditional use means long history rather than trial evidence. Skip chamomile if you react to ragweed, daisies, or marigolds.
Licorice is one of the few herbs NCCIH singles out as having promising evidence in the mouth — specifically, oral rinses for canker sores (NCCIH on licorice root, 2025). The safety side matters here and is covered below; the fuller picture is in the guide to licorice root’s uses and limits.
The tannin astringents: oak bark, rhatany, tormentil, bistort
This is the group traditional European herbal medicine leans on hardest, and the honest label for all of them is traditional use with a plausible mechanism. Tannins bind proteins in inflamed tissue, which tightens and dries the surface and reduces irritation. That is a real chemical effect. It is not the same as a trial showing your gums got better.
European regulators recognize them on traditional grounds. Oak bark is registered for “symptomatic treatment of minor inflammation of the oral mucosa,” prepared at 20 g of bark per litre of water and used for no more than a week (European Medicines Agency, 2010). Rhatany root carries a similar indication for “minor inflammations of the mouth and throat such as stomatitis, gingivitis and pharyngitis,” on the strength of laboratory anti-inflammatory, antimicrobial, and astringent activity (ESCOP monograph on Ratanhiae radix).
Both are worth knowing in more detail before you brew anything: oak bark dosage and safety limits and rhatany root preparation.
Sage belongs in the same tier. The EU monograph lists it for “relief of inflammations in the mouth or the throat” at 2.5 g in 100 mL of boiling water, three times daily, and explicitly does not recommend it in pregnancy, breastfeeding, or under age 18 (European Medicines Agency, 2016).
Popular, but the evidence isn’t there yet
Neem. A systematic review found only three randomized trials, all running two to four weeks, all with unclear risk of bias. Neem looked similar to chlorhexidine, but the appraisal was blunt: the short duration and poor reporting “precludes the drawing of firm conclusions” (Dhingra & Vandana review, appraised 2016).
Tea tree oil. NCCIH lists gum disease among the uses where there is not enough evidence, and adds a hard warning: tea tree oil should never be swallowed, because taking it orally can cause confusion, unsteadiness, inability to walk, and coma (NCCIH on tea tree oil, 2025).
Myrrh. Long tradition, thin human data. Memorial Sloan Kettering notes only a few small human studies and flags a case report of myrrh antagonizing warfarin (MSKCC on myrrh, 2021).
Oil pulling. The ADA’s position is unambiguous: “there are no reliable scientific studies to show that oil pulling reduces cavities, whitens teeth or improves oral health,” and it does not recommend the practice (ADA MouthHealthy on oil pulling).
How to make and use a herbal mouth rinse
The published monographs are consistent enough to give you a working method.
| Herb | Preparation | How often | How long |
| Oak bark | 20 g bark per 1 L water, simmer, cool | Several times daily | Up to 1 week |
| Sage leaf | 2.5 g in 100 mL boiling water, steep, cool | 3 times daily | Up to 1 week |
| Chamomile flower | 1–5 g in 100 mL water, steep, cool | Several times daily | Up to 1 week |
| Rhatany root | About 1.5 g simmered in 150 mL water 10–15 min | 2–3 times daily | Up to 2 weeks |
| Green tea | Brew normally, cool to room temperature | 1–2 times daily | No monograph; use short-term |
Sources: EMA oak bark, 2010; EMA sage leaf, 2016; EMA chamomile flower, 2015; naturalhealthmessage guide to rhatany.
A few rules that apply to all of them:
Swish for 30 to 60 seconds and spit. Do not swallow. Do not rinse immediately after brushing with fluoride toothpaste — you will wash the fluoride off; wait a while, or use the rinse at a different time of day.
Never apply an undiluted essential oil to your gums. Clove, tea tree, and peppermint oils are concentrated enough to burn mucous membranes.
Two weeks is the outer limit for self-treating. Every monograph above says the same thing: if symptoms persist past a week, stop guessing and get the mouth looked at.
And keep brushing. A rinse that replaces brushing is a downgrade, whatever is in it.
Safety, side effects, and interactions
Most of these preparations are low-risk used briefly, in the mouth, and spat out. The risks cluster around swallowing them, taking them during pregnancy, and combining them with medication.
Don’t swallow it
Tea tree oil taken orally causes serious neurological symptoms (NCCIH, 2025). Clove oil in quantity causes acute liver injury, with infants at highest risk (LiverTox). Tannin-heavy decoctions can irritate the stomach. Spit, always.
Children under 6 should not use mouthrinse at all, because their swallowing reflex is not reliable (ADA, 2026). The EU monographs for sage and oak bark do not recommend either below age 18 for lack of data.
Pregnancy and breastfeeding
Sage and oak bark are both “not recommended” in pregnancy and lactation in their EU monographs, on the basis that safety has not been established. Chamomile carries the same note for most preparations.
Licorice is a firmer no. Large amounts during pregnancy — around 250 g of licorice per week — raise the risk of delivery before 38 weeks (NCCIH, 2025). Goldenseal should not be used by anyone pregnant or breastfeeding, and should never be given to infants, because berberine can harm newborns (NCCIH on goldenseal, 2025). Myrrh may stimulate the uterus (MSKCC, 2021).
If you are pregnant, a warm salt-water rinse is the sensible default, and it is what dentists recommend anyway for a sore mouth (MedlinePlus on tooth abscess).
Medication interactions
Ask a pharmacist before combining any of these with prescription drugs — particularly if you swallow them as a tea rather than spitting.
- Licorice interacts with corticosteroids, and glycyrrhizin raises blood pressure and drops potassium. Even low daily doses shifted renin, aldosterone, and home blood pressure in a 2024 study (NCCIH, 2025). If you have hypertension or heart rhythm problems, leave it alone.
- Goldenseal meaningfully changes how the body handles other drugs. In one NCCIH-funded study it cut metformin levels by roughly 25% — enough to matter for someone managing type 2 diabetes (NCCIH, 2025).
- Myrrh has been reported to reduce warfarin’s effect (MSKCC, 2021).
Product quality is its own issue: some commercial goldenseal has been found to contain herbs not listed on the label (NCCIH, 2025).
Two plants to keep out of your mouth
Comfrey, swallowed. Comfrey contains pyrrolizidine alkaloids that the liver converts into toxic metabolites, causing sinusoidal obstruction syndrome and severe liver injury. In 2001 the FDA advised supplement manufacturers to pull oral comfrey products from the market, and infants are especially susceptible (LiverTox: Comfrey; MSKCC, 2022). A mouth rinse is a swallowing risk by definition. The detail on comfrey’s topical-only safety window is worth reading before you go near it.
Cinchona bark. Its active alkaloid is quinine, which the FDA has warned is associated with serious and life-threatening reactions including thrombocytopenia, hemolytic uremic syndrome, and QT prolongation, with fatalities reported. Quinine is approved only for uncomplicated malaria (FDA, 2012).
Teething babies
Nothing herbal goes on an infant’s gums. The FDA warns against benzocaine and lidocaine teething products — benzocaine for the risk of methemoglobinemia, lidocaine for heart problems, brain injury, seizures, and death — and against teething jewelry (FDA, 2024). The American Academy of Pediatrics adds homeopathic teething tablets containing belladonna or coffea cruda to the avoid list (HealthyChildren.org, 2025).
What both recommend instead: massage the gums with a clean finger, or give a firm rubber teether that is not frozen and not liquid-filled.
When to stop rinsing and call a dentist
Herbal rinses are for minor, short-lived irritation. These are not that.
Call your dentist if:
- Gums bleed, stay swollen, or hurt for more than a week or two
- Gums pull back and teeth look longer, or teeth feel loose
- Chewing hurts, or bad breath persists no matter what you do
- A canker sore has not healed after two weeks, or you get them more than two or three times a year (MedlinePlus on canker sores)
- You have a throbbing toothache that will not quit, or a pimple-like bump on the gum — both point to an abscess (MedlinePlus on tooth abscess)
Go to urgent care or the ER now if you have severe swelling of the jaw or face, fever with mouth pain, or any trouble swallowing or breathing. A dental infection that spreads is a medical emergency, not a rinse-and-wait situation. Call 911 if breathing is affected.

Frequently Asked Question
Can herbs reverse gum disease?
Gingivitis — the early, reversible stage — improves with daily brushing, cleaning between the teeth, and professional cleanings, and an herbal rinse may help alongside those. Periodontitis, where gums detach and bone is lost, requires periodontal treatment. No rinse rebuilds lost attachment.
Is a herbal mouthwash as good as chlorhexidine?
In trials lasting two to four weeks, several herbal rinses performed similarly to chlorhexidine on plaque and gum inflammation scores — but those trials were small and mostly low quality, and none tracked people long enough to know what happens over a year. Chlorhexidine has stronger and longer-standing evidence; its main drawback is brown staining.
Which herb helps a toothache fastest?
Clove. It is the only one with a controlled human trial showing a numbing effect comparable to 20% benzocaine. Use whole cloves or a well-diluted oil, never the undiluted concentrate, and treat it as a bridge to a dental appointment rather than a fix.
Can I use a herbal rinse while pregnant?
Warm salt water, yes. Beyond that, most oral herbal monographs say safety in pregnancy has not been established, and licorice and goldenseal have specific warnings against use. Ask your dentist or OB before using anything else.
How long can I keep using a herbal rinse?
The European monographs cap self-treatment at one week for oak bark, sage, and chamomile, and about two weeks for rhatany. If symptoms have not settled in that window, the problem needs a diagnosis rather than a stronger rinse.
Does oil pulling work?
The ADA says no reliable studies show it reduces cavities, whitens teeth, or improves oral health, and it does not recommend the practice.
