According to your description, your back teeth may have "locking" deformity. In your case, you may have mandibular deviation. Need to check whether it is caused by bone or simple tooth inclination. Simple dental problems are relatively easy to correct. If there is jaw deformity, orthognathic surgery may be needed. Specific problems can be solved concretely. In short, there will be a solution, and there is no age limit (18 years old if orthognathic surgery is performed). I suggest you correct it as soon as possible. Unilateral chewing can easily cause joint problems.
