A cavity rarely announces itself early. Many people feel nothing until the decay is deep, which is why a small spot can turn into a bigger, costlier problem. Knowing the early signs of a cavity helps you book a dental exam while treatment is still simple.

Early signs of a cavity to watch for

• Sensitivity to hot, cold or sweet foods that lingers after you swallow.
• White, brown or black spots on a tooth surface, especially near the gumline or in the grooves of back teeth.
• Food catching in the same spot, or floss that shreds between two teeth.
• A mild toothache or pain when you bite down.
• Persistent bad breath or an unpleasant taste that brushing does not fix.

Why a dental exam finds what you cannot see

Decay often starts between teeth or under the surface, where a mirror will not show it. During a checkup, your family dentist looks closely at each tooth and may use dental X-rays to spot tooth decay before it causes pain. Catching it early usually means a small, quick filling instead of a root canal or crown.

Simple habits that lower your cavity risk

• Brush twice a day with a fluoride toothpaste and clean between teeth daily.
• Cut back on how often you snack or sip sugary drinks, since frequency matters as much as quantity.
• Drink water after coffee, juice or sweets.
• Keep up regular dental cleanings and exams so small problems are caught early.
