When are Dental Fillings required at the Dentist for a Cavity?

If you’ve ever had a toothache or noticed a tiny hole in your tooth, you’ve probably wondered, “Do I need a dental filling?”

Cavities are a common issue that most people face at some point. Fortunately, there’s a simple and effective solution – dental fillings. However, when exactly are they necessary, and is a dental filling always required to treat a cavity?

This blog will break down the when and why of dental fillings, helping you understand the signs and what your local dentist at Clearview Dental Clinic in Milton considers before recommending treatment.

What Is a Cavity, and How Does It Form?

A cavity forms when your tooth’s enamel, the hard outer layer, becomes damaged by tooth decay.

This decay is caused by a build-up of bacteria in your mouth. Over time, these bacteria produce acids that wear down your enamel, creating a small hole in your tooth.

If left untreated, this hole will get larger and deeper, eventually leading to more serious dental problems like infections or even the need for a root canal.

That’s where dental fillings come in. They are used to restore your tooth to its original shape and stop decay from causing further damage.

What Does a Dentist Look for When Checking for Cavities?

When you visit a dental office, your orthodontist will look for signs of tooth decay during a regular check-up. They use a variety of methods to detect cavities, including:

Visual Examination

Your dentist will visually inspect your teeth for any noticeable signs of decay or damage, like dark spots or holes.

Dental X-rays

Sometimes, decay isn’t visible on the surface. X-rays help your dentist spot hidden cavities between teeth or below the gum line.

Tooth Sensitivity

If you’ve experienced sensitivity to hot, cold, or sweet foods, it may be a sign of tooth decay, which your dentist will assess during the visit.

When Is a Dental Filling Required?

Not every little spot of decay will need a filling right away, but your dentist will recommend one when:

 1. The Cavity Is Too Large to Repair on Its Own

Small spots of decay may sometimes be managed with improved dental care or fluoride treatments. However, when a cavity gets too large, a filling becomes necessary to stop further damage.

2. The Decay Has Reached the Dentin

If the decay has passed through the enamel and into the softer layer underneath (called dentin), a dental filling is required to prevent it from spreading.

3. You Have a Cracked or Broken Tooth

Sometimes, teeth can crack due to injury or biting down on something hard. A filling can repair the crack and prevent further damage.

4. You Want to Protect a Weak Tooth

Fillings can also be used to support a tooth that is weakened from damage, reducing the risk of future breaks or cracks.

Different Types of Dental Fillings: What’s Best for You?

At Clearview Dental Clinic, we offer a variety of filling materials, each with its benefits. Your dentist will recommend the best option based on your cavity’s size, location, and budget.

a. Composite Fillings

These are a popular choice because they can be made to match the natural color of your tooth.

Composite resin fillings are durable and blend seamlessly with your smile. They work well for smaller fillings and are commonly used in front teeth or areas visible when you smile.

b. Amalgam (Silver) Fillings

Amalgam fillings are strong and durable, making them an excellent choice for molars that endure a lot of pressure from chewing.

However, they are silver in color, so they’re more noticeable than composite fillings.

c. Gold Fillings

On the other hand, gold fillings are used if you want something tough and long-lasting.

However, they are more expensive than other types of fillings and take longer to place because they are custom-made in a dental laboratory.

d. Ceramic Fillings

These are made of porcelain and are another durable, tooth-colored option. They resist staining and can last a long time but tend to be more expensive.

What Happens During the Filling Process?

If your dentist at Clearview Dental Clinic decides you need a filling, don’t worry – the process is straightforward and typically pain-free.

• Numbing the Area

First, your dentist will numb the area around the tooth to ensure you feel comfortable during the procedure.

• Removing Decay

Next, they’ll carefully remove the decayed part of your tooth. This is done to stop the spread of decay and prepare the tooth for the filling.

• Placing the Filling

After the decay is removed, your dentist will place the filling material into the cavity. The filling will be shaped to fit your tooth perfectly and restore its original function.

• Polishing the Filling

Finally, your dentist will polish the filling to ensure that it’s smooth and comfortable and that your bite feels normal.

What Happens If You Ignore a Cavity for Too Long?

Ignoring a cavity can lead to more serious dental problems down the road.

If decay isn’t treated in time, it can spread deeper into the tooth and eventually reach the pulp – the soft tissue inside the tooth.

Once the pulp becomes infected, you might need a root canal or even an extraction to remove the infected tooth.

By catching and treating cavities early with simple tooth fillings, you avoid these more invasive and costly procedures.

Regular visits to your family dentist at Clearview Dental Clinic are the best way to catch cavities early and prevent damage from occurring again.

How Can You Prevent Cavities in the Future?

Good oral hygiene is your first line of defense against cavities. Here are some tips to help keep your teeth strong and healthy:

1. Brush Twice a Day: Use fluoride toothpaste to strengthen your natural tooth enamel and remove plaque.
2. Floss Daily: Flossing removes food particles and plaque between your teeth, which your toothbrush can’t reach.
3. Visit Your Dentist Regularly: Regular check-ups also ensure any problems are caught early before they become serious.
4. Eat a Healthy Diet: Limit sugary snacks and drinks, as they can contribute to tooth decay. Munch on soft vegetables if you’re hungry instead.
