Deep Dental Decay: Filling, Root Canal, or Extraction?
Even with consistent brushing and flossing, cavities develop at some point in the life of 90% of adults. When a cavity progresses to deep decay,

Brushing, flossing, and regular dental visits go a long way in keeping teeth healthy, but sometimes cavities develop despite your best oral hygiene efforts. When decay progresses beyond the surface and becomes severe, it’s important to act quickly. The good news? Modern dental treatments can address even advanced decay effectively.

Here at Jason Ray, DDS, in Santa Monica, California, we treat dental decay with fillings, root canals, and extractions. Which treatment is right for you depends on several factors. Read on to learn more about each of these options for treating cavities and deep decay.

How decay affects your teeth

To grasp how decay develops and spreads, it helps to understand your tooth’s structure.

The tough, outermost layer of your tooth is called the enamel. Made of a mineral that’s the hardest substance in your body, enamel protects the inner layers but isn’t indestructible.

Cementurm is what’s found at the tooth’s root. This bone-like tissue helps anchor teeth to your jaw and protects the layer underneath.

Beneath the enamel and cementum, sits dentin, which contains microscopic canals that can transmit sensations, leading to sensitivity when exposed.


At the core of your tooth is the pulp, a vital layer containing nerves, blood vessels, and connective tissue. Once decay reaches this layer, it often causes pain and infection.

The stages of tooth decay

Tooth decay doesn’t happen overnight. Recognizing its stages can help you take action before it progresses too far.

  1. Enamel demineralization
    The first signs of decay appear as small white spots on the enamel, indicating mineral loss.
  2. Enamel decay

Without intervention, these spots develop into cavities, creating small holes in the enamel that may look light brown.

  1. Dentin decay

As decay penetrates deeper, it reaches the dentin, often causing sensitivity and faster cavity growth.

  1. Pulp damage

Decay that reaches the pulp can cause toothaches, gum inflammation, and dark discoloration of the tooth.

  1. Abscess formation

At this stage, the decay can lead to an abscessed tooth, characterized by severe pain, swelling, and risk of infection spreading to other areas.

We can help you recognize the early signs of decay at regular dental cleanings and appointments and take action to prevent its progression. This is why visiting our office for check ups at least twice per year is so important.

Timely treatment to save your tooth

You should act early when you notice dental decay. Our restorative dentistry services offer several options to treat cavities and preserve your natural teeth.

Cavity fillings are appropriate for early-stage decay. Fillings repair and seal the cavity, preventing further damage.

If decay compromises your tooth’s structure, Dr. Ray may place a crown to provide additional support and protection. Crowns are custom-made to fit your tooth perfectly and blend seamlessly into your smile.

When decay reaches the pulp of your tooth, a root canal removes infected tissue, cleans the area, and seals it to prevent reinfection. In many cases, Dr. Ray adds a crown for extra durability.


In cases of extensive damage, removing the tooth may be the best option to protect your overall oral health. Extracting a severely decayed tooth prevents infection from spreading to other teeth and tissues.

Protecting your smile

Deep cavities and tooth decay don’t have to mean the end of your tooth. With prompt care, you can restore your oral health and maintain a strong, healthy smile. If you’re experiencing tooth pain or suspect decay, don’t wait to seek treatment.
