How can I address tooth sensitivity after getting a dental crown?

Some post-operative sensitivity after crown preparation or cementation on a vital tooth (containing a living pulp or nerve) can be expected.

This tends to happen if there was previous decay or an old filling that is close to the pulp. The vibrations from cleaning out the decay or removing the old filling can cause transient pulpal irritation which can result in cold sensitivity.

If the sensitivity occurs after cementation of the crown, there could be cement washout from underneath or some plaque trapped underneath the crown during cementation. Plaque CAN and commonly does form underneath apparently well-fitting temporary crowns.

If the pulp is able to recover, then the symptoms eventually clear without further treatment.

If the symptoms persist or become worse, then a root canal treatment may eventually be needed.

The tooth may feel sensitive after the crown is placed. For the majority, the sensitivity goes away within a couple of weeks after treatment as the tooth gets accustomed to the crown.

Using simple analgesic medications can help manage the pain in the meantime. For example, ibuprofen is often recommended. It helps to reduce the associated pain and make the patient feel more comfortable.

Some sensitivity of the surrounding gums is common following the placement of a dental crown. This is due to the irritation from the dental cement. In most cases, a topical anaesthetic like benzocaine (Orajel) which is readily available at most pharmacies is able to help relieve this.

In addition, a toothpaste for sensitive teeth may also be useful.

Also, sometimes when the crown is too high, it disrupts the natural occlusion. Hence causing the sensitivity faced.

If the pain continues beyond several weeks or it is severe, it may be necessary for patients to seek dental advice to investigate the situation.
