Signs That You May Need a Dental Filling

Dental Fillings: What Are They?

If you are experiencing dental pain then your dentist may recommend fillings to help restore the strength and appearance of cracked, damaged teeth or cavities. 

Why are dental fillings needed?

Tooth fillings can fix fractures, cracks, or tooth decay. They help restore functionality to your tooth and in some circumstances, dental fillings may also provide a change in the cosmetic appearance of your teeth.

When might I need a dental filling?

A dentist will be able to examine your teeth and determine if a dental filling is the right treatment option for you. Here are some of the signs you may note if you think you may be in need fo a filling. If you experience any of these, schedule an appointment with your dentist:

1. You feel a sharp or throbbing pain in your tooth.
2. When you examine your teeth, you see a hole or dark spot. 
3. Your tooth is broken or chipped. 
4. Your tooth feels rough to the touch. 
5. Food keeps getting stuck between certain teeth. 
6. An existing tooth filling has broken or cracked. 
7. You've lost a tooth filling and need a replacement.

What are the different types of dental fillings?

Dental fillings can be made of a number of materials, from amalgam to composite, porcelain and gold. While each of these materials is safe and long-lasting, they also each have their own advantages and disadvantages when it comes to repairing a cavity or decay. Our dentists provide some more information on each type of filling below:

Porcelain Fillings Are a Strong Option

Also called inlays and onlays, porcelain fillings are brittle, hard, and made in combination with metal. Made in a dental lab and sent back to your dentist to place, these strong, tooth-coloured dental restorations are typically used on molars as they are more durable and longer lasting than a regular dental filling. 

You’ll usually need to attend two dental appointments so your porcelain filling can be placed in your mouth.

Composite Fillings Provide a Natural Feeling

Because they are very similar in colour to natural teeth, composite fillings are great for blending in with all of your natural teeth.

They look and feel natural, and are popular with patients who are concerned with how amalgam (grey) fillings may appear on teeth that are visible when they smile.

Dentists like composites because they are easy to sculpt and shape onto a tooth, and bond naturally to a tooth. This means your dentist won’t need to remove as much existing enamel when preparing the tooth.

Your dentist will remove tooth decay and add bonding material to the inside of the hole so the filling can be placed. Composite resin is then layered in the hole.

A curing light is used to harden each layer. When the last layer of resin has hardened, the filling will be carefully shaped to match your natural teeth.

Gold Fillings Can Offer Ongoing Durability

Cast gold fillings are made using a model of your tooth. Created from a mix of gold combined with other materials such as copper and silver, a cast gold filling is created in a dental lab and sent back to your dentist.

It will then be cemented in place inside your mouth. Though this type of filling is considered the most durable (typically lasting 20 years or more) it is also the most costly. You'll also require at least two dental appointments to have it placed.
