A temporary crown is a protective cap placed over a prepared tooth while the permanent restoration is fabricated in a dental laboratory. It is common for this interim device to feel “weird” or noticeably different in the mouth. The temporary crown safeguards the underlying tooth structure, prevents shifting, and maintains the space needed for the final crown. These unfamiliar sensations are a normal part of the process.
Understanding the Common Sensations
Patients often notice a feeling of bulkiness or slight over-contouring compared to the natural tooth. The temporary crown may feel larger or less finely detailed. This change in shape can affect how the opposing teeth meet, making the bite feel slightly “high” or uneven. If the temporary crown is misaligned, it can create pressure points that cause soreness or pain when chewing.
Many patients report a rougher texture on the surface or edges of the temporary material. This roughness contrasts sharply with the smooth enamel of natural teeth. The margins, where the temporary meets the gum line, may be more detectable, sometimes causing mild irritation. The prepared tooth is highly sensitive, often reacting with sharp discomfort to hot or cold foods and drinks. This temperature sensitivity occurs because the temporary crown material does not insulate the tooth effectively.
Why Temporary Crowns Feel Different
The distinct sensations are primarily due to differences in material and placement compared to permanent crowns. Temporary crowns are typically fabricated from softer, less durable materials, such as acrylic or composite resin. These materials do not offer the same smooth, polished surface or strength found in final crowns made of porcelain, ceramic, or metal alloys.
The crown is secured using a temporary dental cement, which is intentionally designed to be weak for easy removal. This temporary adhesive does not create a tight, perfect seal at the margins, which can allow for minor leakage. Because they are not custom-crafted from an exact mold, the contour and marginal fit are generally less precise than the final, highly customized permanent crown.
Essential Care and When to Call the Dentist
While living with a temporary crown, practice careful chewing and oral hygiene to maintain its security. Avoid chewing hard, crunchy, or sticky foods, such as caramel or gum, which can easily dislodge the crown. Chewing on the opposite side of the mouth is recommended to reduce pressure on the restoration. When brushing, use a soft-bristled toothbrush and clean the area gently.
Flossing technique must be modified to prevent lifting the temporary crown off the tooth. Instead of pulling the floss up and out, slide it out sideways or pull it through the contact point. Patients should contact their dentist immediately if the crown falls off completely or feels very loose. Other warning signs include sharp, throbbing, or severe pain that persists for more than a week, or any noticeable chip or fracture.
