You Google your symptoms.
You get 50 different answers.

Your tooth hurts. You search "why does my tooth hurt" and find everything from "it's nothing" to "you need a root canal." Some articles say wait it out. Others say go to the ER. None of them know your situation.

That confusion is expensive. People either panic and rush to the ER for something a regular dentist could handle, or they wait too long and a $200 filling turns into a $2,000 crown. You deserve a clearer starting point.

Common questions about dental symptoms

Why does my tooth hurt when I bite down?

+

Pain when biting usually points to a cracked tooth, a deep cavity, or a filling that sits too high. Sometimes it's an infection at the root. If the pain happens every time you chew, see a dentist within a few days. In the meantime, chew on the other side and avoid very hard foods.

What does it mean when my gums bleed while brushing?

+

Occasional bleeding can happen if you just started flossing or switched to a harder toothbrush. But if your gums bleed every time you brush, that's usually gingivitis, the early stage of gum disease. The good news: gingivitis is reversible with better brushing, daily flossing, and a dental cleaning.

Should I go to the ER for a toothache?

+

Go to the ER if you have facial swelling that's spreading toward your eye or throat, a fever over 101F with tooth pain, or trouble breathing or swallowing. For severe tooth pain without those signs, an emergency dentist is usually faster and cheaper than the ER.

Why are my teeth suddenly sensitive to cold?

+

Cold sensitivity often means your enamel has worn thin or your gums have pulled back, exposing the softer layer underneath. Whitening products, acidic foods, and grinding your teeth at night can all cause it. Try a sensitivity toothpaste for two weeks. If it doesn't improve, see your dentist.

Can I treat a dental symptom at home?

+

Some symptoms respond to home care. Saltwater rinses help with mild gum swelling. Sensitivity toothpaste can reduce cold sensitivity. Over-the-counter pain relievers work for mild toothaches. But home care is a bridge, not a fix. If any symptom lasts more than a week or gets worse, you need a dentist.

How do I know if my symptom is serious?

+

Three signs that something needs urgent attention: pain that wakes you up at night, swelling in your face or jaw, and any symptom that's getting worse instead of better. When in doubt, DentaSmart's free symptom quiz can help you figure out how urgent it is.
