When we think of braces or aligners, wires and brackets usually take the spotlight. But modern orthodontics uses many other tools to guide your teeth and bite into perfect alignment. One such unsung hero is the posterior bite plane.
What is a Posterior Bite Plane?
A posterior bite plane is a flat acrylic platform that’s often part of a removable retainer or a fixed orthodontic appliance. It sits over your back teeth (molars and premolars) and prevents them from making contact when you bite down.

Why is it Used?
Your orthodontist might recommend a posterior bite plane to:
- Correct deep bites (also called deep overbites)
- Allow front teeth to erupt properly
- Reduce stress on overclosed jaws
- Assist in jaw development in growing children
How Does It Work?
By blocking the back teeth from touching, this appliance shifts the pressure forward, encouraging your front teeth to align and your jaws to find a better vertical balance.
Will It Feel Uncomfortable?
At first, it may feel unusual like most orthodontic devices. But with a little patience, your mouth will adapt quickly. Your dentist will also monitor its fit and function through regular visits to make sure you stay comfortable.

Final Thoughts
The posterior bite plane may be a small addition to your treatment plan, but it can create a big difference in how your teeth come together. If your orthodontist recommends it, trust that it’s part of a smarter path toward a healthier bite and a balanced smile.
