Preventing Postoperative Sensitivity After Dental Fillings

Now, more patients ask their dentists for white fillings, because when they laugh, speak and smile, they want their teeth to look normal. White fillings, also called composite fillings, are made from tooth-colored materials that return a decayed or previously filled tooth to its natural appearance. Have a look at causes and treatments – Eastport Dental Centre for more info on this.

In general a composite filling requires only one visit, during which the tooth is cleaned and repaired. Compared with other dental restorations, one advantage of composite fillings is that they allow less of the healthy part of a tooth to be removed to keep the filling in place. This is because of the tendency of composite materials to bond adhesively to the teeth.

Postoperative sensitivity to the tooth in composite restorations continues to be a normal, but unpredictable, dental problem. This complication is even more unforgiving when serious sensitivities arise on non-sensitive teeth prior to the restoration. Despite the careful use of dentin bonding agents, dentists and patients face the everyday question of sensitivity. Sometimes those restorations need to be reworked by the dentist. For rare cases, the dentist has to treat the sore teeth with root canal therapy.

Practitioners have increasingly developed several prevention approaches to address the problem of sensitivity. A combination of two or more of the following “desensitizing” techniques may be required when postoperative tooth sensitivity is expected. Clinicians have identified and supported various variations of the methods. The combination technique that I used with almost 100 percent success follows: o Use of self-etching primers (such as Kuraray SE Bond, Kuraray America, New York City); o Applying tooth-desensitizing (GLUMA) solutions to the tooth prior to filling; o Laying a thin (about half a millimeter thick) resin-reinforced glass ionomer liner on deepest cavity surfaces; and o

Other key events which are not related to composite placement can also induce sensitivities. For example: o Accidentally burning the pulp during the preparation of the cavity, particularly when the remaining dentin is less than 1.5 mm thick and when insufficient water coolant is sprayed during the preparation of the cavity; o Not removing all decay; and o Bonding failure due to water and saliva contamination Composites are preferred for obvious cosmetic purposes. Whether the decayed area is wide or is subject to intense chewing pressure, your dentist can prescribe another substance or restorations. Certain types of white fillings include composite inlays and inlays and onlays made from porcelain. Inlays and onlays are used to repair teeth which are badly affected by wear or decay. When aesthetics are of concern they can be put on the chewing surfaces of the back teeth.

The white fillings cost more than other dental products. Many patients however find these natural-looking restaurations well worth the extra expense. White fillings can need periodic replacement, as with other dental materials. When the filling edge gradually pulls away from the tooth, bacteria may get between the filling and the enamel and may eventually cause new decline under the current filling. Some people in the freshly filled tooth may experience some sensitivity to the hot and cold temperatures for a few days or as long as a week. If the sensitivity goes on past this time, please contact your dentist. Approximately 1 percent of those chronic sensitive teeth may need root canal therapy.
