Repair Poorly Fitting, Damaged or Broken False Teeth

Whether false teeth break or don't fit quite well, the best solution is to visit a dentist. Dentures may look natural, but they do not respond to changes in the shape of your mouth, and can become damaged if they're dropped. Caring for or replacing dentures incorrectly can also harm them, which is why it's important to act according to the following conditions.

Maintaining Dentures

Careful daily maintenance keeps dentures from becoming misshapen, which would weaken their structure and raise their risk of breaking if you were to drop them on a hard surface. Therefore, dentures should be removed from the mouth and cleaned once per day, usually at night. Be sure to do this over a towel or a sink full of water to avoid similar breakage or damage if they slip out of your hands. After rinsing your dentures in cool, clean water, brush them with a soft-bristled toothbrush such as Colgate® 360°® Sensitive Pro-Relief, and place them in a denture cleaning solution overnight. Allowing dentures to dry out can change their shape so they no longer fit properly.

Poorly Fitting Dentures

Jaws and gumlines can change shape over time, and this can cause false teeth to become loose or ill-fitting. Your dentist will even see signs that your dentures don't fit well at a checkup, or you may notice the dentures feel loose yourself. Stay alert to gums that are irritated or cause difficulty chewing, as well. Under these circumstances, your dentist can fix the problem by relining, rebasing or remaking the product entirely. The University of Tennessee Health Science Center explains that relining applies new surface material to the base of the dentures, whereas rebasing involves replacing the denture base. Alternatively, your dentist may decide to remake the dentures with both a new base and new set of teeth.

Broken or Damaged Dentures

Dentures don't just break or become damaged when dropped on hard surfaces; they can also succumb to general wear and tear. The American Dental Association (ADA) suggests partial dentures can incur this harm if the patient bites down to fit them into place. This bends the clasps that attach the dentures to the natural teeth.

Keep in mind that only a dentist can fix damaged or broken false teeth. Attempting to fix them yourself can be dangerous to your health. Over-the-counter glues contain harmful chemicals, and should not be used for repairing dentures. Another hazard may come from fixing dentures incorrectly – sometimes beyond repair – leading to irritation and mouth sores that need additional oral maintenance on your part. A dentist can often fix simple damage within a day, but a complicated repair may require sending the denture to a dental lab.

Implant-Supported Dentures

Implant-supported dentures may face their own complications wherein the teeth loosen from their base and supporting screws, causing the denture to become loose or the implants to become unsteady as a result. Clenching or grinding the teeth, along with an uneven fitting at the outset, also make implant-supported dentures more likely to break or loosen. And as with other types of false teeth, a dentist is the best person to fix problems with implant-supported dentures.

For speed or budgetary reasons, it may be tempting to try to fix your poorly fitted, damaged or broken dentures yourself – but only a dentist has the skill, materials and experience to repair them. It may seem convenient, but tending to them yourself can be more harmful to your health than it's worth. Plus, a dental visit takes only a short time to provide a long-term, effective solution.

Top Oral Care Tips for DENTURES


  • Don't let dentures dry out – place them in a denture cleanser soaking solution or in plain water when you're not wearing them. Never use hot water, which can cause dentures to warp.
  • Brush your dentures – brushing dentures daily will remove food and dental plaque, and help prevent them from becoming stained.
  • Take care of your mouth – brush your gums, tongue and palate every morning with a soft-bristled brush before you insert dentures. This stimulates circulation in your tissues and helps remove plaque.
  • Consult your dentist – see your dentist if dentures break, chip, crack or become loose. Don't be tempted to adjust them yourself — this can damage them beyond repair.
