How do I know if I have a cavity?!
Question:
How do I know if I have a cavity?
How do you know if you have a cavity without going to the dentist? What are some signs?
Answers:
Some cavities cannot be seen with a visual examination, such as decay on the sides in the space between teeth. The only way to catch those cavities before the tooth crumbles would be to take some X-rays.
That's why regular 6-month cleanings are important. The dentist can detect cavities while they are small and inexpensive to fix.
By the time a tooth starts to hurt from a cavity, it's too late. You will need a root canal, post + core, and crown in order to save the tooth. $2000+.
