Numerous individuals take dental veneers in order to enhance their smile. Nevertheless, people often ask one question: Why is my tooth under my veneer turning black? You may find it concerning when you see a dark shade. The good news is that doctors could easily treat the majority of causes. In this blog, you will know the causes, remedies, and preventive measures in simple and understandable terms.
Why Is My Tooth Turning Black Under My Veneer?
A tooth under a veneer becoming dark may occur for a number of reasons. Despite the fact that veneers are resilient and durable, the underlying natural tooth may experience problems. Due to this, discoloring or shadow might be present. In most cases, decay, trauma, staining, or veneer issues bring about the dark color. Thus, patients should take dental checkups to determine the precise cause.
Tooth Decay Under the Veneer
Tooth decay is one of the most widespread causes of discoloration. Although veneers wrap the front side of the tooth, bacteria can still invade the sides if the bond is poor. Wear and tear is likely to occur over time, and consequently, the tooth becomes brown or black internally. This dark color might be revealed in the veneer.
Lack of oral health, high-energy foods, and neglecting dental procedures put one at risk of decay.
Leakage at the Veneer Edges.
Another cause of dark discoloration is the leakage of the margins. In case dentists do not seal the veneers correctly, food particles and bacteria slide between the veneer and the tooth surface. With time, staining begins. Veneers are stain-resistant, but the natural tooth behind them is not. Thus, leakage results in internal staining, which is visible.
Trauma or Injury to the Tooth
If the tooth that was to have the veneer sustained damage prior to the procedure, internal bleeding can occur. This bleeding is capable of darkening the tooth. The change of color can persist even when the veneer has been laid. As a result, the tooth appears black under the veneer, especially when exposed to light.
Veneer Material and Age
At times, it is not the tooth but rather the veneer. Old veneers are liable to lose lustre and become dull. Poor quality veneers also color or even darken. Also, the veneers are thin, and as such, when the underlying tooth is dark, it will be visible after a few years.
What Are Root Canal Issues?
In case a tooth has already been treated in the root canal, it can be darkened gradually because of internal processes. The dark shade, in this case, can be seen behind the veneer. On the one hand, even when we set the veneer to conceal the defects, we cannot entirely prevent the internal discolouration as well.
Why is my tooth turning black under my veneer?
This fact is not to be overlooked. Since the veneers are only superficial, they are incapable of treating problems in the internal teeth. Hence,a dental checkup is required to determine why it has happened and to repair it. The sooner it is detected, the more easily it is treated.
The way Dentists resolve this issue.
There are several treatment modalities based on the cause:
Elimination and Replacement of Veneer.
In case the veneer is aged or leaking, it is stripped. The tooth is cleansed, repaired and a new veneer is inserted. This imparts a fresh and natural appearance.
Treating Tooth Decay
In case of decay, the dentist cleans the infected region and replenishes the tooth. Another veneer or a crown is bonded after treatment.
Internal Bleaching
In case the discoloration is internal in nature (due to internal staining or traumas) then internal tooth whitening can be advised. This is carried out prior to the laying of another veneer.
Root Canal Treatment
In case of infection, RCT is done. The veneer or crown is once more put on after the restoration of the tooth.
