A temporary dental filling is a protective seal placed over a prepared tooth while waiting for a permanent restoration, such as a crown or definitive filling. This material shields the vulnerable inner tooth structure, including the dentin and nerve, from the oral environment. You can and should brush a temporary filling, but you must do so with extreme care to prevent dislodging the softer material. Gentle, consistent cleaning is necessary to prevent infection or tooth sensitivity until your next appointment.
The Right Way to Clean a Temporary Filling
Maintaining oral hygiene requires specialized technique to protect the temporary material, which is not as durable as a permanent filling. Use a soft-bristled or extra-soft toothbrush, applying minimal force to the area with the temporary filling. The brushing motion should be a gentle, sweeping action away from the gumline, rather than a harsh scrubbing motion that could lift the material.
Use a non-abrasive toothpaste, as abrasive pastes can wear down the surface of the temporary filling more quickly. After brushing, rinse with lukewarm water to wash away debris without causing abrupt temperature changes that could affect the material. Proper flossing requires even more caution, as the dental floss can easily snag and pull the temporary filling out.
When cleaning between the teeth surrounding the temporary filling, gently slide the floss down to the gumline, but do not pull it straight back up and out. Instead, release one end of the floss and gently slide the strand out sideways from the gumline, away from the contact point of the filling. This technique prevents the upward force that can catch the edge of the filling and pull it from the tooth. Your dentist may advise avoiding flossing around the tooth entirely until the permanent restoration is placed.
Key Precautions While the Filling is in Place
Temporary filling materials, such as zinc oxide eugenol or glass ionomer cements, are softer and less strongly bonded than permanent materials, making them susceptible to damage. To protect the filling, avoid chewing on the side of your mouth where the temporary material is placed, especially during the first few hours after placement. This action reduces the pressure exerted on the fragile material, allowing it to set fully and remain intact.
Dietary choices are important while the temporary filling is in place. You should avoid foods that are hard, crunchy, or sticky, such as nuts, hard candy, caramels, or chewing gum. Sticky foods can pull the filling out as you chew, while hard foods can cause the material to fracture under biting force. Avoid exposing the tooth to extreme temperature variations, such as rapidly alternating between very hot and ice-cold drinks, as this may weaken the filling or increase sensitivity.
Recognizing and Handling Damage or Loss
Temporary fillings are designed to wear down slightly over time, but complete loss or a large fracture requires immediate attention. If you notice a sudden hole, feel a sharp edge with your tongue, or experience increased sensitivity, the filling may be damaged or gone. The exposed tooth structure is vulnerable to bacterial contamination, which can lead to infection, or to shifting of the surrounding teeth.
If the filling falls out, immediately contact your dental office to schedule a replacement appointment. While waiting, rinse your mouth gently with warm salt water to keep the area clean and minimize the risk of infection. For discomfort or sensitivity, use a small amount of dental wax or an over-the-counter temporary filling repair kit to cover the exposed area. Prompt replacement is necessary because the temporary filling is the only barrier preventing further decay or damage.
