Patients who have teeth pulled are often unaware of the impact that losing a tooth can have on their smiles. Of course, that’s not the only way to lose teeth, either. Advanced periodontal disease, trauma, and other causes often cause adults to lose teeth. When that happens, the mouth begins to change because of the gap created by missing teeth, and the resulting changes are often permanent. If left for too long, quality of life issues set in. That’s why Dr. Gainer recommends replacing those teeth right away.
