Teeth are remarkably strong, but they are not indestructible. Over time, everyday activities such as chewing, brushing and drinking can gradually affect the outer layer of your teeth. This process is known as tooth wear.
A small amount of wear can be a normal part of getting older. However, excessive tooth wear may lead to sensitivity, changes in appearance, discomfort and a greater risk of dental problems. The good news is that many causes of tooth wear are linked to everyday habits, which means there are practical ways to reduce the damage.
What Is Tooth Wear?
Tooth wear happens when the hard enamel covering your teeth is gradually lost. Enamel does not grow back once it has been permanently worn away, so protecting it is important.
There are three main types of tooth wear: abrasion, attrition and erosion. They can occur separately or at the same time.
Abrasion is usually caused by physical forces acting on the teeth. Brushing too aggressively, using a hard-bristled toothbrush or regularly chewing on objects such as pens can contribute to this type of wear.
Attrition occurs when teeth rub against each other. Grinding or clenching your teeth, particularly during sleep, can place considerable pressure on the enamel.
Erosion is caused by acids. These acids can come from food and drinks, such as citrus fruits, soft drinks, sports drinks and fruit juices. Stomach acid from conditions such as reflux or frequent vomiting can also contribute.
Common Causes of Tooth Wear
Teeth Grinding and Clenching
Bruxism, commonly known as teeth grinding or clenching, can gradually flatten and damage the teeth. Some people grind their teeth while asleep without realising it.
Signs can include flattened tooth edges, jaw soreness, headaches when waking up and increased tooth sensitivity. If you notice these symptoms, it is worth discussing them with a dental professional.
Acidic Foods and Drinks
Frequent exposure to acidic foods and drinks can soften enamel. This does not necessarily mean you need to completely avoid acidic foods. The frequency of exposure often matters.
Regularly sipping soft drinks, energy drinks or fruit juice throughout the day can keep exposing your teeth to acid. Having acidic drinks with meals and limiting how often you consume them can help reduce this exposure.
Brushing Too Hard
Brushing harder does not mean brushing better. Excessive pressure can contribute to enamel and gum damage, particularly when combined with an abrasive toothpaste or a hard toothbrush.
A soft-bristled toothbrush and gentle, controlled movements are generally a better approach.
Poor Oral Health Habits
Plaque and gum problems can affect the overall health of your mouth. While tooth wear is not directly caused by plaque, poor oral hygiene can make existing dental problems more difficult to manage.
Brushing twice a day with fluoride toothpaste, cleaning between your teeth and attending regular dental appointments can help maintain a healthy mouth.
Dry Mouth
Saliva plays an important role in protecting teeth. It helps wash away food particles, neutralise acids and support the natural repair of enamel.
A dry mouth can therefore increase the effects of acid and raise the risk of tooth damage. Dehydration, some medications and certain health conditions can contribute to reduced saliva flow.
How Can You Prevent Tooth Wear?
Preventing tooth wear starts with simple changes to your daily routine.
Use a soft toothbrush and avoid applying excessive pressure when brushing. Replace your toothbrush or electric toothbrush head when the bristles become worn.
Be mindful of how often you consume acidic drinks and foods. Rather than sipping an acidic drink slowly over several hours, have it with a meal where possible. Drinking water afterwards can also help rinse your mouth.
Do not brush immediately after consuming acidic food or drinks. Acid temporarily softens enamel, and brushing straight away may increase the amount of wear. Waiting around 30 minutes before brushing gives your saliva time to help neutralise the acids.
If you grind or clench your teeth, speak with a dentist about suitable options. Depending on the cause and severity, they may recommend a night guard or other treatment.
It is also important not to ignore tooth sensitivity, chipped edges, flattened teeth or changes in your bite. These can sometimes be early signs of excessive tooth wear.
When Should You See a Dentist?
Tooth wear can develop gradually, so you may not notice it until significant changes have occurred. Regular dental check-ups allow problems to be identified before they become more complicated.
A dentist can assess the condition of your enamel, look for signs of grinding or acid erosion and determine whether your tooth wear is within the expected range. If treatment is needed, addressing the cause is just as important as treating the visible damage.
Protect Your Teeth for the Long Term
Some tooth wear is unavoidable as the years pass, but excessive wear does not have to be. Paying attention to your brushing technique, diet, drinking habits and any signs of grinding can make a meaningful difference.
Your teeth are designed to last a lifetime, and good daily care combined with regular professional checks can help keep them strong, comfortable and functional for as long as possible.
