Missing teeth: Patients who have lost teeth may wish to consider getting partial dentures to avoid adverse effects on their general health and appearance. Partial dentures as a tooth replacement option keep your gums, jaw, and facial muscular tissues active and engaged by ensuring that they maintain their structural integrity. Shifting teeth: If your teeth move or become loose in your mouth, you may be getting closer to wearing dentures. Teeth usually loosen as a result of periodontal disease or tooth decay. These dental problems have advanced when there’s an increasing gap between teeth, and loose teeth are observed. Chewing problem: There is difficulty in chewing due to missing teeth. You cannot bite or chew a variety of foods properly, so your digestive system will be unable to process those bigger chunks of food, resulting in indigestion.
