My teeth are weak. and paining?

Dental care: Unfortunately without seeing a dentist, there is no way to find out what is wrong & without treatment it tends to get worse over time and eventually leads to tooth infections and loss of teeth. Try to get to a dentist as soon as possible. In the meantime, brush & floss after meals for at least two minutes & avoid foods high in sugar as well as sticky starchy foods which contribute to cavities.

Must see dentist: Teeth are the one should stay with you , for your whole life , with any neglect you will lose them , not a good thing at 24 . Call your dentist immediately for an appointment , do not neglect , you need the beautiful smile.
