Three Causes of Flat Teeth
Are you noticing your teeth looking shorter or flatter than they used to? While some natural wear is normal with time, there are instances where flat teeth are due to other factors. This can be a sign that something isn’t quite right with your bite or jaw alignment. Flat teeth can result from a variety of causes, some more obvious than others. If not intercepted, aggressive tooth wear, damage, or TMJ problems are likely to develop.
Let’s explore three primary reasons behind this condition: misaligned bite, bruxism and sleep apnoea.
A Misaligned Bite
One of the most common culprits behind flat teeth is a misaligned bite, or what dentists call malocclusion. Each of our teeth is designed in such a way that it bites against the opposing tooth in a particular manner. When that doesn’t happen due to jaw irregularities or tooth misalignment the teeth wear down prematurely. Although enamel is very hard, enamel rubbing against itself is quite damaging. Over time, this results in flat spots or worn-down surfaces.
Flat teeth caused by malocclusion can also lead to jaw discomfort, headaches and difficulty chewing. Correcting the alignment with braces or other orthodontic treatments can help prevent further wear and alleviate these symptoms.
Bruxism (Grinding and Clenching Habit)
At times, people grind their teeth without realising it. This subconscious habit, called “bruxism,” usually occurs while you’re sleeping or as the result of daily stress, anxiety or concentration. Some people notice they’re clenching their teeth on the daily commute or while working at their desks. Others don’t realise there’s a problem until the tension builds up to a headache or migraine at the end of the day or when they wake up in the morning. This repetitive grinding or clenching can wear down the enamel, causing the teeth to appear flattened over time.
Our dentists at SDG recommend custom night guards to protect the teeth from further damage. Reducing stress, practising relaxation techniques and addressing any underlying sleep issues can also help minimise grinding habits.
Sleep Apnoea
While it might not seem like an obvious link at first, sleep apnoea can be another factor contributing to flat teeth. Sleep apnoea is a condition where your airway becomes blocked during sleep, causing interruptions in breathing. As a natural result, the body starts to fight for air intake. One of the ways it shows is by the jaw clenching itself tightly as facial and airway muscles fight to bring in oxygen.
When sleep apnoea and teeth grinding occur together, the result is accelerated wear on the teeth, leading to the characteristic flattening. If you suspect that sleep apnoea is contributing to your dental issues, it’s important to seek medical advice. If you’re exhibiting other symptoms of sleep apnoea, such as chronic fatigue, high blood pressure, or a large neck circumference, you may want to get screened for a sleeping disorder.
Treatments for sleep apnoea often involve CPAP (Continuous Positive Airway Pressure) machines, which help maintain an open airway during sleep. Addressing the underlying sleep disorder can reduce grinding and protect your teeth from further damage.
