Understanding the Common Causes of Dentin Hypersensitivity

Posted on: 1 November 2017


Dentin hypersensitivity, which is also commonly known as tooth sensitivity, is a widespread condition which affects people of all ages. In general, an individual with sensitive teeth will experience pain or discomfort when their teeth are in contact with triggers. For example, acidic foods, hot and cold foods, cold air and touch will initiate an ache in the affected tooth. This condition occurs when dentin is exposed. The natural tooth is covered by enamel, which protects the internal structures. If this layer is lost, the more delicate dentin is left open, leading to hypersensitivity. Here are the common issues which could be causing your dental sensitivity 

Dental Decay

Tooth decay can cause dentin hypersensitivity problems. Typically, this form of deterioration occurs due to the presence of sugars in the mouth. In simple terms, when there is sugar residue in your mouth, the bacteria in your oral cavity will consume it. Then, they will produce acid as a by-product. This corrosive fluid will cause the enamel to dissolve and the dentin to be uncovered. As a result, you will feel pain when your mouth is exposed to triggers. If the affected tooth is not treated, the dentin will also eventually be dissolved. This will cause the infection of the pulp cavity. You can avoid these problems by upholding good hygiene and consulting a dentist for regular check-ups and early treatment.

Corrosive Dental Products

Your teeth might be experiencing sensitivity issues due to the use of corrosive dental products. Often, individuals cause their teeth harm by being overzealous in their oral practices and not understanding the consequences of using some products. For instance, some mouthwashes contain acidic compounds which can wear away the enamel. You should always make sure that your product is a neutral fluoride rinse. Tooth whitening toothpaste may also have abrasive action, so you should regulate your usage or replace it. Additionally, you should choose a soft-bristled toothbrush.

Underlying Disease

Dentin hypersensitivity could be an indication of an underlying problem. In simple terms, it could be a small symptom of another disease. For instance, if you have gingivitis, you might experience tooth sensitivity. This condition must be treated before the hypersensitivity issue can be resolved. Also, people with behavioural problems such as teeth grinding and biting on hard objects will experience continued sensitivity due to constant enamel wear. 

Sensitive teeth can compromise your quality of life. Therefore, if you are experiencing pain or general discomfort, you should consult your dentist for diagnosis of the underlying problem and subsequent treatment
