Tooth Cavity Stages: How Cavities Form & Progress

 Ever wondered how a tiny spot on your tooth can turn into a big problem? You’re not alone. We’re discussing tooth cavities, and understanding how they develop is the first step to supporting your oral health.

In this blog, we’ll take a simple journey through the different stages of a tooth cavity, from a hardly-noticeable spot to something that really hurts. We’ll also share some easy tips on how to stop them in their tracks. So, let’s get started!

What is a Tooth Cavity?

First things first, what exactly is a tooth cavity? Think of it as a little hole in your tooth. These holes are caused by tooth decay, which happens when bacteria in your mouth create acids. These acids slowly eat away at the outer layers of your tooth, creating a tiny opening that can get bigger over time. This process is a bit like rust on a car – it starts small and can spread if you don’t take action.

Stage 1: White Spot Lesions

The very first sign of a cavity isn’t a hole at all. It’s actually a white spot on the surface of your tooth. This is called a “white spot lesion.” At this stage, the enamel (the super-hard, protective outer layer of your tooth) has started to lose minerals. It’s like the enamel is becoming a little bit weaker and more porous. It might look a bit chalky or dull compared to the rest of your tooth.

This is the earliest stage to catch a cavity, when it may still be reversible. At this point, it’s not a true hole yet, and it can often be reversed. Your dentist can use treatments like fluoride varnish to help replenish the minerals in your teeth. And, of course, brushing with a fluoride toothpaste can help strengthen your enamel and reduce the risk of the cavity progressing.

Stage 2: Enamel Decay

If the white spot isn’t treated, the decay continues. The acids produced by the bacteria continue to dissolve the minerals, and eventually, the enamel begins to break down. This is where a small hole, or a “lesion,” begins to form. At this stage, the decay is still only in the enamel. You might start to feel a little bit of sensitivity when you have something cold or sweet, but you might not feel anything at all.

This is the point at which a dentist will likely recommend a filling. A filling is a simple procedure where the dentist removes the decayed part of the tooth and fills the hole with a material like composite resin. This stops the decay from spreading deeper into the tooth. It’s a bit like patching a small hole in a tyre before it gets bigger and causes a flat.

Stage 3: Dentin Decay

If the cavity isn’t fixed at the enamel stage, it will continue to get bigger and deeper. The next layer it reaches is the dentin. Dentin is the layer just under the enamel. It’s softer than enamel and full of tiny tubes that lead to the nerve of the tooth. Because dentin is softer, decay can progress more quickly once it reaches this layer.

When the cavity reaches the dentin, you’ll probably start to feel more pain and sensitivity. That’s because the nerves in your tooth are getting closer to the action. You might feel a sharp pain when you eat something hot or cold, or when you have a sugary drink. At this stage, a filling is still the most common treatment. However, because the decay is deeper, the filling might be a bit bigger.

Stage 4: Pulp Involvement

Now we’re getting to the serious stuff. The pulp is the very centre of your tooth. It contains all the blood vessels and nerves. If the cavity reaches the pulp, it’s a big problem. The bacteria and acids can cause an infection and inflammation in the pulp. This is called pulpitis.

When the pulp is involved, the pain can be constant and throbbing. It might be so bad that it keeps you up at night. The tooth might also feel sensitive to pressure when you bite down. At this stage, a simple filling won’t be enough. The dentist will likely need to perform a root canal treatment. This is a procedure where the dentist cleans out the infected pulp and seals the tooth to prevent further infection. After the root canal, a crown is often placed over the tooth to protect it from breaking.

Stage 5: Abscess Formation

This is the most severe stage of a tooth cavity. If the infection in the pulp isn’t treated, it can spread all the way to the tip of the root and into the bone and gums. This forms a pocket of pus called a dental abscess.

An abscess can cause significant pain and swelling. You might notice swelling in your cheek or jaw, a fever, and a bad taste in your mouth from the pus. An abscess can also be dangerous if the infection spreads to other parts of your body. At this stage, the dentist will need to drain the abscess and, in some cases, might have to remove the tooth entirely. An abscess is a medical emergency, and you should see a dentist or doctor right away if you think you have one.

How Cavities are Diagnosed

So, how do dentists spot these cavities? It’s not always as simple as looking in your mouth. While a dentist can often see a large cavity, they use a few other tools to find it, especially in the early stages.

  1. Dental Examination: Your dentist will use a small mirror and a probe to look at the surface of your teeth for any signs of decay, like white spots or holes.

  2. X-rays: These are an important tool that can help detect decay not visible during a standard examination. X-rays can reveal decay that’s hidden between your teeth or under old fillings, which a dentist may not be able to see with the naked eye.

  3. Patient’s Symptoms: Your dentist, such as dentist Redfern, will also ask you questions about any pain or sensitivity you’re feeling. Your symptoms can give them clues about how far the decay has progressed.

Preventing Tooth Cavities at Each Stage

The best treatment for a cavity is to prevent it from happening in the first place! Here are some simple tips for preventing tooth cavities at every stage:

  1. Stage 1 (White Spot Lesions): At this stage, it’s all about remineralisation. Brush your teeth twice a day with a fluoride toothpaste. Fluoride helps strengthen your enamel and can even reverse these early signs of decay. Your dentist might also recommend a fluoride varnish treatment.

  2. Stage 2 (Enamel Decay): Keep up the good work with your brushing and flossing! This is an ideal time to be especially diligent about your dental hygiene. If you have a small cavity, a filling is the best way to stop it from getting bigger.

  3. Stage 3 (Dentin Decay): Now that the decay is deeper, it’s crucial to get a filling as soon as possible. Delaying treatment increases the risk of needing more complex dental procedures.

  4. Stages 4 & 5 (Pulp and Abscess): This is where prevention becomes about avoiding the pain and hassle of a root canal or tooth removal. The key is to have regular check-ups with your dentist. They can spot a cavity long before it gets to these painful stages.

Conclusion

Understanding the stages of a tooth cavity is like having a road map for your dental health. It shows you how a tiny problem can grow into a big one if it’s not taken care of. Most cavities can often be prevented with good oral hygiene and regular dental visits, and even if you do get one, catching it early makes all the difference.

Remember, brushing twice a day, flossing daily, and seeing your dentist for regular check-ups are the best ways to keep your smile healthy and bright. If you are in Redfern and would like to book a dental check-up, you can contact our clinic to arrange an appointment.

FAQ

Q: Does a cavity always hurt? 

A: No, not at all! In the early stages (white spot lesions and enamel decay), you might not feel any pain or sensitivity. That’s why regular dental check-ups are so important.

Q: Can I stop a cavity from getting worse on my own? 

A: You can’t get rid of a cavity on your own once it’s started, but you can help slow it down by practising excellent oral hygiene. However, a dentist is the only person who can truly stop the progression and fix the cavity.

Q: What’s the difference between a cavity and tooth decay? 

A: Tooth decay is the process that happens when acids break down your tooth’s enamel. A cavity is the hole or damage that results from that process. So, tooth decay is the cause, and a cavity is the result.

Q: What’s the best way to prevent cavities? 

A: The best way is to brush your teeth twice a day with a fluoride toothpaste, floss once a day, limit sugary snacks and drinks, and see your dentist regularly.
