How to Sand Down Dentures

Dentures are prosthetic replacements for partial or full sets of teeth. Typically dentures can be removed for regular cleaning and maintenance, but they can be fragile and break or become damaged. A number of companies offer denture repair kits for use at home. Kits contain repair powder and a mixing agent to prepare a putty that can create a rough surface on the dentures. Sanding of the repaired denture is a key step in completing the repairs to the dentures 2.

How To Sand Dentures

Repair dentures based on repair kit directions 2. Generally the repairs consist of removing the damaged tooth, replacing with the new tooth contained in the kit and securing the replacement tooth with a putty created by combining a powder polymer and liquid polymer. The denture should be placed in warm water to bond the replacement tooth to existing dentures. Adhere to the manufacturer’s instructions for the time frame that dentures should soak in warm water. Do not use hot water for this process, because the putty mixture may not adhere properly. Gently dry dentures after a predetermined time in warm water.

Sand the replacement tooth. The replacement tooth area may feel rough, so sanding reduces this problem. Use a piece of fine sand paper or emery paper for the sanding process. Most kits include the appropriate item for sanding that works best with the product. Sanding gives a smooth feel to the replacement tooth and assists in ensuring a better fit for the denture when in use. Gentle sanding is sufficient to achieve a smooth surface.

Polish the tooth after sanding with products included in the home kit, or gently brush with toothpaste. This step should result in restoring the denture to its original condition. After repair is complete, dentures should fit the wearer comfortably and securely.


The use of over-the-counter glues to repair dentures is not recommended. Glues may contain toxins that may seep into the gums, and the toxins are not healthy for the denture wearer. Glues also tend to weaken the denture and make daily cleaning difficult. A denture home repair kit may not be the best alternative in all cases. Consult a professional oral care provider for assistance.
