Tooth Sensitivity: Causes and Solutions

You may develop tooth sensitivity for a number of different reasons. We will provide a full dental examination to determine the underlying cause of your tooth sensitivity. Some common causes of tooth sensitivity may include:

Foods and Beverages

Acidic and sugary foods and drinks can break down the tooth enamel over time. If you consume acidic foods and beverages, be sure to clean your teeth regularly and hydrate. Drinking water regularly helps wash away acids and sugars left in the mouth. Hydrating can also increase saliva production, which is key to keeping the mouth healthy. 

If you notice signs of tooth wear from acidic foods and beverages, we can offer cosmetic treatments like veneers or dental bonding. These treatments cover teeth to create brighter, fuller, and healthier smiles.

Hard Brushing

If you aggressively brush your teeth, it can lead to enamel damage. Additionally, brushing too hard can expose the dentin within the tooth. Dentin is a dark under-layer beneath the outer tooth enamel. As hard brushing wears down the enamel, it can discolor and damage teeth.

Ultimately, brushing your teeth too hard and using hard-bristled brushes can create pain and damage. It’s best to use a soft-bristled toothbrush and take your time when you brush your teeth.


Also known as teeth clenching and grinding, bruxism is a problem that wears down teeth over time. Patients who experience bruxism can have TMJ disorders which also cause jaw problems. Often, TMD patients clench or grind their teeth unconsciously when stressed or during sleep. Many patients with TMD can also experience tooth wear and damage that leads to increased tooth sensitivity. 

Wearing a custom-made TMJ night guard can prevent further damage to teeth and also prevent the teeth from grinding together. Additionally, wearing this night guard can alleviate other symptoms of TMD, including headaches and jaw pain.

Tooth Damage and Decay

You can experience tooth sensitivity if you have worn, chipped, or broken teeth. Tooth injuries can sometimes even expose the dental pulp or the blood vessels, cells, and nerves within the tooth.

It’s also important to treat the pulp if it is exposed to bacteria. We may recommend a root canal to remove the pulp and fill the tooth with composite material. Covering and protecting damaged teeth with dental crowns can also prevent further damage to teeth.
