What Pain When Biting Might Mean
When a tooth hurts only when you bite or chew, it is telling you that something specific is wrong. Unlike constant pain that might come from an infection, bite pain is usually triggered by pressure on a damaged area.
Common Causes
Cracked tooth: One of the most common causes. The crack opens slightly when you bite, irritating the nerve. It closes when you release, which is why the pain comes and goes.
Cavity reaching the inner layer: When decay gets deep enough, biting pressure pushes on the weakened tooth structure and causes pain.
High filling or crown: If a recent filling or crown sits too high, it absorbs more force than it should. This causes soreness and can lead to bigger problems.
Tooth infection: An infection at the root can make the tooth tender to pressure. You might also notice swelling or a bad taste.
Gum disease: Advanced gum disease loosens teeth, making them painful when you bite.
What to Do Now
- Avoid chewing on the painful side. Give the tooth a break while you figure out what is going on.
- Check for recent dental work. If you had a filling or crown recently, it might just need a small adjustment.
- Use DentaSmart for clarity. Upload a photo and get AI insights about what might be causing your pain. Then visit your dentist with better information.
