Is an implant possible for a second premolar tooth if there is a crossbite?

Most Likely yes: There are many factors that can decide if you are a good implant candidate ( such as amount of available bone, amount of room between the upper and lower jaw, etc. ) the fact alone that you have a cross-bite is not as important as other possible issues. In addition our office advises almost all our implant patients to have a nite-guard fabricated as well.

Should be ok: Many things go into the planning and placement of an implant and crown, not just a crossbite. Discuss your options with your dentist.

Possible, but best?: In itself, a crossbite does not preclude the placement and restoration of a dental implant. Whether you should or should not have one done, is a very different story. Good dentists don't just fill holes. Discuss your issue with at least one good general dentist or prosthodontist to see what options you have and what would be the "ideal" treatment for your circumstances.

Anything's possible: But may not be the best solution. Consider having teeth straightened (orthodontist) to create the best possible platform on which your restorative dentist can replace missing teeth.

Probably possible: But, any abnormal biting and grinding forces can effect the long term stability of your implant. If you could have your cross bite fixed first it would be ideal.
