"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 (eugenol) ✓ With reservations
Clove contains eugenol, a compound with proven anesthetic and antibacterial properties. In fact, eugenol is used in professional dentistry as a component of temporary filling materials. Placing a whole clove or clove oil on a sore tooth can provide temporary relief of 15-30 minutes.
Caution: eugenol in prolonged contact with the gums can cause chemical burns to soft tissue. Don't leave it in for more than a few minutes. It is not treatment — it's a temporary palliative.
Salt water rinse ✓ Useful
A teaspoon of salt in a glass of warm water is a mild natural antiseptic. It reduces surface bacteria, lessens mild gum inflammation and helps drain superficial pus in some cases. It's safe and can be repeated several times a day.
Limitation: doesn't penetrate inside the tooth or resolve deep infections.
Ice or cold compress ✓ Useful for swelling
Applying cold to the outside of the cheek (wrapped in cloth, 15 minutes on / 15 minutes off) reduces swelling and pain in cases of acute inflammation.
Caution: never apply ice directly on the tooth — extreme cold on an exposed or inflamed nerve generates intense pain.
Garlic ⚠️ Partial
Garlic contains allicin, a compound with modest antimicrobial properties. Chewing garlic or placing it on the tooth can provide a slight superficial antibacterial effect.
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
Used as a rinse (a teaspoon in water) to neutralize acidity in the mouth. Useful after vomiting or after very acidic meals. But it has no effect on dental pain or on infections.
Caution: baking soda as a regular brushing paste is abrasive and wears down enamel over time.
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
Placing an aspirin directly on the gum is a popular remedy that causes severe chemical burns in gingival tissue. Aspirin works swallowed (orally), not by direct contact. If you need a painkiller, take it with water.
When is a toothache the nerve and home remedies are not enough?
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:
- Pain persists more than 48 hours despite painkillers.
- There is visible swelling in the face, cheek or neck.
- The pain is throbbing and worsens when you lie down (sign of pulpitis).
- There is fever associated with dental pain (sign of spreading infection).
- 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.
And if the tooth that hurts already had a root canal, no remedy applies: what it needs is an evaluation for root canal retreatment.
What does the endodontist do that no remedy can?
Severe toothache generally indicates that the dental pulp is compromised — infected, inflamed or necrotic. No rinse, clove or painkiller resolves that. What is needed is:
- Precise diagnosis with digital radiography to see what's happening inside the tooth.
- Treatment of the cause: root canal therapy if the pulp is compromised, drainage if there is an abscess.
- Complete elimination of infection with instrumentation and disinfection of the canal system.
- 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.
- Don't combine medications on your own or raise the dose because "it isn't working": if the pain reliever isn't enough, the problem is inside the tooth and needs treatment, not more pills.
- Never place a pill on the tooth or the gum: pain relievers work swallowed with water, not by contact.
- Don't use antibiotics without a prescription. Self-medicating with antibiotics doesn't resolve the cause and contributes to bacterial resistance.
- If the pain comes with fever, swelling in the face or neck, or difficulty swallowing, do not wait: message us on WhatsApp right away so we can arrange urgent care.
The best remedy is the one that resolves the cause
Home remedies have their place: as temporary relief, as family tradition, as a gesture of care. But when pain is persistent, intense or accompanied by swelling, the cause is inside the tooth and only a professional can resolve it. At Clínica Endodontics in San Miguel, we diagnose and treat the cause of the toothache, not just the symptom. Message us on WhatsApp.
