Garlic on a toothache may ease the pain for a short time. When you crush or chew fresh garlic, it makes allicin, a natural substance that can fight some germs. But garlic does not fix what is causing the pain, and it can burn your gums if you leave it on too long. Think of it as a short-term help until you can see a dentist.
Most toothaches have a clear cause, such as a cavity, a cracked tooth, or an infection. Only a dentist can find that cause and treat it. In this guide, Noah Smile Group explains what garlic can and cannot do, how to use it safely, and which signs mean you need dental care soon.
Common Causes of Toothaches
A toothache is a sign that something in or around the tooth needs care. According to Cleveland Clinic and MedlinePlus, these are the common causes of a toothache:
- Tooth decay, which makes a hole (a cavity) in the tooth
- An abscess, which is a pocket of pus caused by an infection
- A cracked or broken tooth
- A damaged filling or crown
- Gum disease
- Teeth grinding or clenching
- Tooth wear or an injury to the jaw or mouth
- A sinus infection, which can make the upper teeth ache
MedlinePlus also explains that pain you feel in a tooth can sometimes start in another part of the body, such as an ear. This is called referred pain.
Does Garlic Help Toothache Pain?
Garlic may ease mild tooth pain for a short time, but it does not stop the problem that causes the pain. Fresh garlic may lower the number of germs around the sore tooth. Some people say the tooth feels a little calmer after they use it.
The cavity, crack, or infection is still there after the garlic is gone. So if you want to know whether garlic helps with tooth pain, the honest answer is yes, a little, and only for a short while. Use it just to get through the time until you can see a dentist.
How Garlic Relieves Toothache
Garlic only starts to work after you break it. A raw clove keeps two things apart inside its cells, a compound called alliin and an enzyme called alliinase. When you crush or chew the clove, these two mix and turn into a new substance called allicin, usually in under a minute (Linus Pauling Institute).
Allicin is the main germ-fighting part of garlic. Once it forms, it touches the sore tooth and gum, and that is where any relief comes from.
Here are the reasons garlic may ease a toothache for a short time:
- Allicin fights germs. In lab tests, it slowed the growth of bacteria tied to cavities and gum disease (Bachrach et al., 2011).
- Fewer germs around the sore tooth may mean a little less irritation.
- Some garlic compounds calmed swelling in lab studies, which may help the area feel a bit better.
Garlic has clear limits, though. It is not a numbing agent, it cannot reach the nerve inside the tooth, and it does not clear an infection at the root. Raw garlic often stings at first, and any relief is mild and short.
Fresh Garlic vs. Garlic Powder vs. Cooked Garlic
If you wonder whether garlic is good for a toothache, the type of garlic matters. Allicin breaks down over time, so crush the clove right before use. Garlic powder has no ready-made allicin, and the amount it can form when wet varies a lot from jar to jar (Linus Pauling Institute).
Heat stops the enzyme that makes allicin, so cooked garlic gives very little. Fresh, raw garlic is the best choice.
Does Science Support Garlic for Toothaches?
There is only a little science on garlic for toothaches. According to a 2011 lab study in the Journal of Medicinal Food, allicin from garlic stopped the growth of bacteria linked to cavities and gum disease. According to the Linus Pauling Institute at Oregon State University, garlic extracts also fight bacteria in lab tests.
But a lab dish is not a real mouth. According to the same institute, studies in people who took garlic by mouth have not shown strong proof that it fights germs in the body. Very few studies, if any, have tested garlic on toothaches in real patients. So the idea makes sense, but no one has proven that garlic eases tooth pain in people.
How to Use Garlic for Toothaches
Here is how to use garlic for toothache relief with the least risk. Use one fresh, raw clove, and keep the garlic on the tooth, not the gum, as much as you can. Before you start, rinse your mouth with warm water to clear away any food.
Method 1: Make a Fresh Garlic Paste
- Peel one fresh clove and crush it with the back of a spoon. Add a small pinch of salt if you like.
- Wait about a minute so the allicin has time to form.
- Use a clean fingertip or a cotton swab to place a small amount on the sore tooth.
- Keep the paste on the tooth and away from the gum line as best you can.
- After a few minutes, spit it out and rinse your mouth well with warm water.
Method 2: Chew a Garlic Clove
- Peel a fresh garlic clove for toothache relief.
- Chew it gently a few times with the sore tooth to release the allicin. If biting down hurts, skip this method and use the paste.
- Keep the chewed garlic off your gums as much as you can.
- After a few minutes, spit it out and rinse with warm water.
With either method, do not press garlic into a hole or crack in the tooth! Small pieces can get stuck there, keep stinging the tissue, and be hard to get out.
How Long to Leave Garlic on a Toothache
Leave garlic on a toothache for only a few minutes. Then spit it out and rinse your mouth with warm water. Never leave it in overnight. Raw garlic can burn the inside of your mouth if it stays too long. According to a published case report, one person kept crushed garlic against the gum overnight to ease a toothache and ended up with peeling tissue and open sores. Stop right away if your gums burn, sting, or look raw. Rinse with cool water, and call a dentist if the soreness does not go away.
Tooth Problems Garlic Cannot Fix
Garlic cannot fix the problem that causes a toothache. It cannot fill a cavity, repair a cracked tooth, or cure a gum infection or an abscess. These problems need a dentist. Depending on the cause, a dentist may use a filling, a root canal, gum treatment, or remove the tooth (MedlinePlus).
Many people look up garlic for tooth infection. But garlic cannot reach an infection deep in the gum or at the root of the tooth. Without treatment, the infection can get worse or spread.
If you are searching for how to use garlic for gum infection, our advice is not to. Swollen, infected gums are tender, and raw garlic can irritate or burn them. Rinse with warm water and call a dentist instead.
Other Home Remedies for Toothaches
Garlic is not your only option at home. According to Cleveland Clinic, some home remedies can give mild relief from a toothache, but pain that does not go away needs a dentist. The table below shows common remedies, how they may help, what to watch for, and where the advice comes from.
Remedy | How It May Help | Main Caution |
Warm salt water rinse | Cleans the area and may soothe gums | Rinse and spit; do not swallow large amounts |
Cold compress on the cheek | May reduce swelling and dull pain | 15 to 20 minutes at a time, with a cloth barrier |
Over-the-counter pain relievers | Reduce pain and inflammation | Follow the label; never place aspirin on the gum |
Clove oil (eugenol) | Mild numbing effect | Dilute it; can irritate gums |
Peppermint tea bag | Mild soothing effect | Use cooled, not hot |
According to the American Dental Association, you should never put aspirin or any other pain pill against your gums, because it can burn the tissue. MedlinePlus also notes that clove is a popular toothache remedy, but there is no good scientific proof that it works.
These remedies may ease the pain for a short time, but none of them can replace treatment from a dentist. They do not fix the cause of the toothache.
Risks and Limitations of Using Garlic
Garlic comes from the kitchen, but that does not make it harmless in a sore mouth. These are the main risks to keep in mind:
- Raw garlic can cause a chemical burn if it stays in place too long.
- It can irritate the gums and leave a painful mouth ulcer.
- Some people are allergic to garlic and may get a rash or swelling.
- Garlic may add to the effect of blood thinners such as warfarin, so ask your doctor or pharmacist first if you take one (Linus Pauling Institute).
The biggest limit is simple. Garlic may calm the pain for a short time, but the cause keeps going, and some dental problems get harder to treat the longer they wait.
When to See a Dentist for Toothache
Garlic and other home remedies can only ease tooth pain for a short time. A toothache that keeps coming back or gets worse is a sign that the tooth needs care. Call a dentist soon if you notice any of these signs:
- Pain that lasts longer than a day or two (MedlinePlus)
- Severe pain, or pain when you open your mouth wide
- Swelling in your gum, face, or jaw
- A fever
- Pus, or a bad taste in your mouth that does not go away
Trouble swallowing or breathing is an emergency. Call 911 or go to the nearest emergency room right away. If a toothache keeps coming back, our team at Noah Smile Group in Brooklyn can help you find the cause. Dr. Edward Chalouh treats tooth pain and repairs damaged teeth.

Conclusion
Garlic on a toothache may ease mild pain for a short time. Use one fresh, raw clove, leave it on the tooth for only a few minutes, and rinse your mouth after. Do not leave it in overnight, and do not push it into a hole or crack in the tooth.
Garlic can help you get through a hard night, but it cannot fix the problem. A dentist can find out what is causing the pain and treat it before it gets worse. If dental visits make you nervous, you can ask about comfort and anesthesia options that help many patients feel more relaxed.
FAQs
Not reliably. Garlic powder holds no ready-made allicin. It may form some when wet, but the amount varies widely, so fresh crushed garlic is the better choice.
Some can ease pain for a short time, such as a salt water rinse, a cold compress, or pain relievers. None of them fix the cause of a toothache.
No study has set a safe number. Keep each use to a few minutes, stop if gums sting, and see a dentist if pain lasts beyond a day or two.
Use a fresh, raw clove, crushed or chewed right before use. Cooked garlic and garlic powder make little or uneven amounts of allicin, so they are less likely to help.
