Knowing your treatment options can make a huge difference when it comes to dental care. You will probably be wondering what the difference is between both the treatments when your dentists tell you that either you have to undergo a root canal or a deep cavity filling.

There is no need for you to worry about as we are here to help you! Our team of dentists at Radiant Dental Care are available to resolve all your doubts and highlight the significance of each treatment. It will help you make an informed decision in the end.

What’s the Difference Between a Deep Cavity Filling and a Root Canal?

Let us first address the basic understanding of both treatments. A tooth cavity filling is used to repair a tooth that has been damaged by the decay but the damage has not reached the pulp.

A root canal is required when the decay or infection has spread to the pulp. It causes pain or even abscess. To put it in simple terms, a filling is like patching up a small hole in a wall, while a root canal is more like repairing the foundation of a house. Both are important, but they serve different purposes.

When Do You Need a Deep Cavity Filling?

A tooth cavity filling is your go-to solution if the dentist catches the cavity early. The following signs will let you know whether you need to undergo a filling or not:

  • Mild to moderate tooth sensitivity.
  • Dark spots or visible holes on your teeth
  • Pain while chewing food

It is a quick and straightforward process. The team of dentists at Radiant will remove the decayed portion of the teeth and fill it with a durable material like composite resin. It helps ensure your filling looks and feels natural.

When Is a Root Canal Necessary?

It becomes necessary to undergo root canal treatment when the infection or decay reaches the tooth’s pulp. It can happen if a cavity is left untreated for too long or if there is a trauma to the tooth. The following signs show that you have to undergo the best root canal treatment in Chennai at Radiant Dental Care:

  • Persistent and severe toothache
  • Sensitivity to cold or hot that lingers
  • Tenderness or swelling in the gums
  • A discolored tooth

The team will remove the infected pulp during the root canal process. Then the tooth is cleaned, disinfected, and sealed. Most of us are surely going to get intimidated while reading, but thanks to advancements in dentistry, the process is more comfortable than ever before.

Root Canal vs Filling Cost: What to Expect?

The Root canal vs filling cost is one of the most common questions that comes to our mind, isn’t it? The cost of filling is on the lesser side when compared to RCT. It is because fillings are a much simpler process when compared to root canals.

However, the exact cost of the treatment depends on various factors like material used, severity of the decay, and your exact location.

For example, the tooth filling cost in Chennai ranges between ₹1,500 to ₹4,000 per tooth. Whereas, the root canal treatment might cost between ₹5,000 and ₹15,000.
