Would my upper premolar extraction affect my palate or maxilla over time? (Photo)

When an upper premolar is extracted, it can lead to some changes over time in the surrounding bone structure, including the maxilla, due to natural bone resorption. Bone loss in the extraction area can affect the adjacent teeth and, in some cases, lead to slight changes in the facial structure, especially if multiple teeth are missing. However, it's less likely to impact the palate directly.
To prevent significant bone loss or shifting of adjacent teeth, options like bone grafting or an implant in the extraction site could help maintain the bone structure and stability of the surrounding area. Replacing the missing premolar with an implant can help preserve the maxilla’s shape and support nearby teeth, which in turn can reduce the likelihood of noticeable structural changes.

Answer is NO. Premolar extraction changes palate shape during orthodontic/braces treatment. Once treatment is over and there is no relapse, palate shape and size will remain the same for the whole life.
