Why won’t my partial go back in after I left it out for a while? The simple answer is teeth shifting. It is important to note that teeth shift for multiple reasons. A partial prevents your teeth from shifting by holding the vacant spaces open. Teeth can shift because of not wearing your partial or retainer, periodontal disease, and grinding your teeth. Even millimeters of movement in your teeth can cause your partial not to fit anymore. This can sometimes happen rapidly. It is best to have your case evaluated by your dentist for treatment options tailored to your needs.

While there are a few potential reasons you may not be able to get your partial in, most likely your teeth have shifted. The purpose of a partial is not only for chewing and aesthetics, but to maintain the positioning of their teeth by occupying open spaces.

Another reason your partial may suddenly not be fitting properly can be grinding. Have you noticed that you clench or grind your teeth while you have had your partial out? Have you noticed daytime fatigue or headaches? You may be grinding your teeth. The extra pressure may have caused your teeth to shift in order avoid the immense amount of extra pressure. Your dentist may suggest using a night guard to protect your teeth from future damage.

Have you noticed you are now able to see more of your tooth structure than before? Have you noticed that your teeth are now slightly mobile? You may have issues getting your partial in place because of oral changes due to periodontal disease. Your dentist will be able diagnose and treat your condition according to your specific needs.
