"Put on a clove." "Chew some garlic." "Rinse with salt water." "Put ice on the outside." If you're Salvadoran, you've probably heard — or given — these tips for a toothache. Home remedies are part of our culture and pass from generation to generation with the confidence of someone who has used them "all their life." But which ones really work? Which are harmless? And which can make the problem worse? Here we evaluate them with a clinical eye.
What helps a toothache at home? The most popular remedies, evaluated
Clove oil: avoid improvised home applications
Eugenol is used in certain dental products with specific formulations and instructions. That does not make a whole clove or concentrated oil a suitable home treatment for every toothache.
Do not place concentrated clove oil on your gum. Ask a pharmacist or healthcare professional about suitable products and how to use them.
Salt water rinse ✓ Useful
An adult who can rinse and spit safely may try half a teaspoon of salt in a glass of warm water. Spit it out rather than swallowing. This may ease some discomfort, but does not drain an abscess or cure an infection.
Limitation: doesn't penetrate inside the tooth or resolve deep infections.
Ice or cold compress ✓ Useful for swelling
A cold pack wrapped in cloth, applied outside the cheek with breaks, may ease some discomfort. Do not place ice directly on skin or on the tooth.
Caution: never apply ice directly on the tooth — extreme cold on an exposed or inflamed nerve generates intense pain.
Garlic: do not place it on the tooth
Properties of a compound in garlic do not establish that chewing it or placing it in a cavity treats a dental infection. Avoid this application.
Reality: the concentration of allicin from chewing is too low to have a real effect on a dental infection. And raw garlic on the gums can cause mucosal burns.
Baking soda ⚠️ Limited
Baking soda is not a treatment for toothache or dental infection. Do not use it as a substitute for evaluation.
A homemade mixture for scrubbing a tooth is not equivalent to a formulated and evaluated toothpaste. Use products according to their instructions.
Alcohol (drinking or rinsing) ✗ Not recommended
A persistent myth: "swish some hard liquor where it hurts." Alcohol irritates soft tissue, dehydrates the mucosa and has no real anesthetic effect on the dental nerve. It can worsen inflammation. Don't do it.
Aspirin on the tooth ✗ Dangerous
Do not place aspirin on the tooth or gum: it can injure tissues. If you need pain medicine, seek advice about a suitable option and follow its instructions.
When to seek dental care
Home remedies are temporary palliatives that may help while you get professional care. But none resolve the cause of pain. You should seek a dental evaluation when:
- Severe, persistent, or worsening pain, or pain not controlled with measures suitable for you.
- Swelling of the face or gum; if it extends to the neck, seek hospital emergency care.
- Throbbing pain or pain disrupting sleep; the symptom alone does not establish a diagnosis.
- Fever with dental pain: urgent evaluation is needed.
- Pain appears spontaneously with no trigger (not just when eating or drinking cold).
- There is visible pus or constant unpleasant taste.
- The tooth has new mobility.
If the tooth has already had a root canal, evaluation assesses the cause of pain and whether retreatment or other care is appropriate. Read more: root canal retreatment.
What does the endodontist do that no remedy can?
Pain can have different causes, including decay, gum problems, a fracture, or pulpal disease. A consultation allows:
- Assessment of symptoms, clinical tests, and X-rays when indicated.
- Selection of care according to the diagnosis: a restoration, root canal treatment, or another option.
- Treatment of the identified cause and planning of follow-up.
- Restoration of the tooth so it continues to function.
What can I take for a toothache while I wait for my appointment?
- An over-the-counter pain reliever, at the dose on the package: it can help you manage the pain while you wait for your appointment. Avoid self-medicating if you are pregnant, take anticoagulants, or have gastritis, an ulcer or kidney disease — in those cases check first.
- Do not combine medicines or increase doses on your own. If pain is not controlled, seek urgent dental care.
- Do not place tablets on the tooth or gum.
- Don't use antibiotics without a prescription. Self-medicating with antibiotics doesn't resolve the cause and contributes to bacterial resistance.
- If you have difficulty breathing or swallowing, or swelling extending to your neck or near your eye, go to a hospital emergency department without waiting for a WhatsApp reply.
The best remedy is the one that resolves the cause
If pain persists, is severe, or comes with swelling, seek care to identify the cause. Clinic hours are Monday–Friday, 8 a.m.–5 p.m., and Saturday, 8 a.m.–noon, subject to availability. If the clinic is closed and you need urgent care, seek an available service.
