Ever noticed your teeth looking a bit different, perhaps a bit dull or sensitive? It could be something called dental erosion. Don’t worry, we’re going to break down what it is, why it happens, and how you can keep your precious tooth enamel safe. Think of your tooth enamel like the tough armour protecting your teeth. When it gets worn down, your teeth become vulnerable.

This article will explain everything you need to know about dental erosion in simple terms. We’ll cover what causes it, the signs to look out for, and most importantly, how to protect your smile.

Dental Erosion

Imagine your teeth have a super-strong, clear outer layer. That’s your tooth enamel. It’s the hardest substance in your body, even tougher than bone! Its main job is to protect the softer, more sensitive parts of your teeth inside.

Dental erosion happens when this strong enamel is slowly worn away by acids. These acids aren’t from bacteria, like in tooth decay; they come from other sources, like certain foods and drinks or even from inside your own body. When enamel erodes, it means it’s literally dissolving away, making your teeth weaker and more prone to problems.

It’s a bit like sand on a beach being washed away by the tide. Over time, if the sand isn’t replaced, the beach gets smaller. Similarly, if your enamel is constantly attacked by acids and doesn’t get a chance to recover, it starts to thin out.

What’s the Difference: Erosion, Decay, and Wear?

It’s easy to get confused between dental erosion, tooth decay, and tooth wear. While they all affect your teeth, they’re pretty different:

  • Dental Erosion: As we just discussed, this is when acids dissolve your tooth enamel. It’s a chemical process. The acids don’t come from bacteria.
  • Tooth Decay (Cavities): This is caused by bacteria in your mouth. These bacteria feed on sugars from the food and drinks you consume. As they eat, they produce acids that attack your enamel. Over time, these acid attacks create holes in your teeth, which we call cavities. So, decay is about bacteria making acid, while erosion is about acids from other sources.
  • Tooth Wear (Attrition and Abrasion): This is physical wear and tear on your teeth.
    • Attrition happens when teeth rub against each other, like from grinding or clenching your teeth. It’s like two rocks rubbing together.
    • Abrasion happens when something else rubs against your teeth, like brushing too hard with a hard toothbrush or biting on hard objects. It’s like scrubbing a surface with something rough.

Think of it this way: erosion is a chemical wash, decay is a bacterial attack, and wear is a physical rub-down. Each one needs a different approach to fix.

Causes of Dental Erosion

A lot of things can lead to dental erosion. It mainly comes down to acids, and where those acids are coming from.

  • Acidic Foods and Drinks: This is a big one! Many popular drinks are very acidic. Think about:
    • Soft drinks (sodas): All types, including diet versions, are highly acidic.
    • Fruit juices: Even 100% natural fruit juices like orange, apple, and lemon juice are acidic.
    • Sports drinks and energy drinks: These are often packed with acids and sugar.
    • Citrus fruits: Oranges, lemons, limes, grapefruits – while healthy, they are acidic.
    • Vinegar: Found in salad dressings and pickles.
    • Some lollies (sweets): Especially sour ones, which are designed to be acidic.
  • Stomach Acid (Reflux): If you have conditions like heartburn or acid reflux (also known as GORD – Gastro-Oesophageal Reflux Disease), stomach acid can come up into your mouth. This acid is very strong and can quickly wear away enamel. Bulimia, an eating disorder, also involves frequent exposure to stomach acid.
  • Certain Medications: Some medicines can be acidic or can cause dry mouth. A dry mouth means you don’t have enough saliva, which is really important for protecting your teeth. Saliva helps wash away acids and also contains minerals that can repair enamel.
  • Low Saliva Flow (Dry Mouth): As mentioned, saliva is your mouth’s natural defence against acids. If you have a dry mouth (xerostomia), whether due to medication, medical conditions, or other reasons, your teeth are much more vulnerable to erosion.
  • Chlorinated Swimming Pools: If you’re a regular swimmer in heavily chlorinated pools, the chlorine can make the water acidic, which can sometimes lead to erosion over a very long time.

Signs of Enamel Erosion

It can be hard to spot dental erosion in its early stages because it’s a slow process. But as it gets worse, you might notice some of these signs:

Early Signs of Enamel Erosion

  • Sensitivity: Your teeth might feel sensitive to hot, cold, or sweet foods and drinks. This happens because the enamel, which protects the nerves inside your tooth, is getting thinner.
  • Discolouration: Your teeth might start to look a bit yellow. This is because as the white enamel wears away, the yellowish layer underneath, called dentine, starts to show through.
  • Rounded Edges: The biting or chewing surfaces of your teeth, especially your front teeth, might start to look more rounded and less sharp.
  • Shiny Spots: Sometimes, you might see shiny, smooth areas on your teeth where the enamel has been polished away by acid.

Advanced Signs of Enamel Erosion

  • Increased Sensitivity: The sensitivity becomes much worse and more frequent.
  • Cracks and Chips: As enamel thins, your teeth become weaker and more likely to chip or crack, especially on the edges.
  • Cupping: On the chewing surfaces of your back teeth, you might see small, round indentations or “cups.” These are areas where the enamel has completely worn away, exposing the softer dentine.
  • Transparent Edges: The very edges of your front teeth might look almost see-through.
  • “Dentine Exposure”: You might see noticeable patches of yellow dentine showing through the enamel.
  • Fillings That Stand Out: If you have fillings, they might start to look like they are sitting “proud” or higher than the surrounding tooth surface. This is because the enamel around the filling has worn away, but the filling itself hasn’t.

How Does Dental Erosion Affect Your Oral Health?

Dental erosion isn’t just about how your teeth look. It can have some serious effects on your overall oral health:

  • Pain and Discomfort: The sensitivity to hot, cold, and sweet can range from a mild twinge to significant pain, making it uncomfortable to eat and drink.
  • Increased Risk of Decay: With thinner enamel, your teeth lose their protective layer. This means they are much more vulnerable to tooth decay (cavities) because bacteria can attack the softer dentine more easily.
  • Need for Complex Dental Work: If erosion becomes severe, you might need more involved dental treatments like crowns, veneers, or even root canals to repair the damage and protect the tooth.
  • Changes in Bite: As teeth wear down, your bite might change, which can lead to jaw pain or other problems.
  • Reduced Quality of Life: Persistent pain, difficulty eating, and concerns about your smile can impact your daily life and confidence.

Who Is at Risk for Erosion?

While anyone can experience dental erosion, some people are more at risk:

  • People who frequently consume acidic drinks: Especially soft drinks, sports drinks, and fruit juices.
  • Individuals with acid reflux or heartburn: Regular exposure to stomach acid.
  • People with eating disorders: Particularly bulimia, due to frequent vomiting.
  • Those with dry mouth: Lack of saliva leaves teeth unprotected.
  • Athletes: Often consume sports drinks and can experience dry mouth during intense exercise.
  • People on certain medications: Which might cause dry mouth or be acidic.
  • Individuals who frequently sip acidic beverages: Sipping means longer exposure to acids.

Professional Treatments for Erosion

While home care is essential, sometimes professional help is needed, especially if erosion is advanced or if you have specific risk factors. A dentist in Leppington or a Harrington Park dentist can offer solutions:

  • Fluoride Treatments: Your dentist can apply stronger fluoride varnishes or gels to your teeth to further strengthen enamel.
  • Bonding: If erosion has caused minor chipping or sensitivity, your dentist can use a tooth-coloured resin to cover exposed areas and restore the tooth’s shape.
  • Veneers: For more significant erosion on front teeth, thin, custom-made shells (veneers) can be bonded to the front surface to improve appearance and protect the tooth.
  • Crowns: If the erosion is severe and has weakened the tooth significantly, a dental crown (a cap that covers the entire tooth) might be necessary to protect it and restore its function.
  • Treating Underlying Conditions: Your dentist can work with your doctor to manage conditions like acid reflux or dry mouth that contribute to erosion.
  • Custom Night Guards: If teeth grinding or clenching is contributing to wear alongside erosion, a custom-made night guard can protect your teeth while you sleep.

Long-Term Effects If Left Untreated

Ignoring dental erosion can lead to a range of problems over time:

  • Increased Sensitivity: This can become chronic and severely impact your ability to eat and drink comfortably.
  • Frequent Cavities: The loss of enamel leaves your teeth highly susceptible to decay, leading to more fillings and potential dental pain.
  • Tooth Fractures: Weakened teeth are much more likely to chip, crack, or even break.
  • Tooth Loss: In very severe cases, erosion combined with decay or fractures can lead to the loss of teeth, requiring more extensive and costly treatments like implants or dentures.
  • Changes in Facial Appearance: Over time, severe wear from erosion can affect your bite and even change the appearance of your face.
  • Higher Dental Costs: Preventing erosion is always cheaper and less invasive than treating its advanced stages.

When to Visit a Dentist in Leppington

It’s a good idea to see your dentist regularly for check-ups, even if you don’t notice any specific problems. However, you should definitely book an appointment if you experience:

  • New or increased tooth sensitivity.
  • Changes in the appearance of your teeth, such as yellowing, dullness, or unusual shininess.
  • Chipping or cracking of your teeth.
  • Any pain or discomfort when eating or drinking.
  • If you know you have risk factors, like acid reflux or frequent consumption of acidic drinks.

Your dentist Leppington or Harrington Park dentist can assess your teeth, identify any signs of erosion, and recommend the best course of action to protect your smile. They can also offer personalised advice based on your diet and lifestyle.
