How do I know if I have a cavity?
Your dentist can discover cavities during your regular dental check-up. The tooth surface feels soft when probed by your dentist with a dental instrument. X-rays can also show cavities before they become visible to the eye.
In advanced stages of tooth decay, you might experience a toothache, especially after consuming sweet, hot, or cold foods or drinks. Other signs of tooth decay are visible pits or holes in the teeth.
