Is it normal to have 34 teeth when you 17 on top bottom?

The typical adult should have 32 permanent teeth. Having 34 teeth at age 17 is not common. Some potential reasons for having 34 teeth include:

- Hyperdontia: This is a condition in which a person develops extra teeth. Hyperdontia can occur in either the upper or lower jaws and can involve one or more teeth.

- Impacted teeth: Impacted teeth are teeth that are stuck in the jawbone and are unable to erupt into the mouth. Sometimes impacted teeth can cause the surrounding teeth to shift and become crowded, which can lead to problems with biting and chewing.

- Supernumerary teeth: These are extra teeth that develop in addition to the normal set of 32 teeth. Supernumerary teeth can occur anywhere in the mouth, but they are most commonly found in the upper jaw.

If you have 34 teeth, it is recommended that you see a dentist or orthodontist to determine the best course of treatment. Depending on the situation, treatment may involve removing the extra teeth, braces to correct any crowding, and other procedures.
