Dental Fillings & Repairs for Cavities

tooth colored fillings near EdmontonCavities and fillings are one of the most common reasons to visit your Edmonton, Alberta dentist. If your tooth is sore and the pain just won’t go away, you could have a cavity. This pain will only get worse over time and the only way to make it stop is by getting the cavity filled. At The Dentists at Northgate, we can perform emergency dental work, but it is always best to come in for yearly checkups, which could even help catch the warning signs of cavities before fillings even become necessary.

While fillings don’t usually require emergency dental care, there are some rare instances when you need to see your Edmonton, Alberta dentist immediately. If you have any of the following symptoms, contact The Dentists at Northgate immediately:

  • Severe toothache
  • A toothache that lasts more than two days
  • A toothache with fever or pain in your ear
  • Severe pain when drinking cold beverages
  • Pain in a tooth that has an old filling

It is important to catch cavities before they become a bigger problem, so at the first signs of discomfort, it’s usually a good idea to schedule a dental appointment in Edmonton, especially if it’s been a while since your last checkup. Cavities affect people of all ages, which is why it’s important to visit a dentist at least once a year.

If a cavity grows deep, a simple filling might not be enough. If you don’t take care of a cavity right away, your tooth nerve might be affected or your tooth could be cracked or broken. This will require a root canal or crown to fix the damage, another reason to get regular checkups and to call us immediately if you notice one of the emergency symptoms above.

If you already have fillings, yearly appointments will allow your Edmonton dentist to monitor these fillings and watch for any signs of wear or damage. Like anything, fillings will wear down over long periods of time, becoming loose or broken. When your filling needs to be repaired or replaced, your regular checkup will let The Dentists at Northgate know before pain and discomfort become an issue.

Types of Fillings

There are two common types of fillings for cavities, amalgam and composite resin. Amalgam fillings are tough, durable fillings made from a composition of different metals such as silver, copper, and tin. Composite resin fillings are newer and can be colored to match your teeth, unlike the silver of amalgam fillings. These are made by a mixture of plastic and glass to make a strong filling for any tooth, front or back.

Whether you need emergency fillings or just want a dental appointment in Edmonton, Alberta for a yearly checkup, call The Dentists at Northgate and our friendly staff will be happy to schedule an appointment for you.

White Fillings (Composite)

A composite (tooth colored) filling is used to repair a tooth that is affected by decay, cracks, fractures, etc. The decayed or affected portion of the tooth will be removed and then filled with a composite filling.

There are many types of filling materials available, each with their own advantages and disadvantages. You and the doctor can discuss the best options for restoring your teeth. Composite fillings, along with silver amalgam fillings, are the most widely used today. Because composite fillings are tooth colored, they can be closely matched to the color of existing teeth, and are more aesthetically suited for use in front teeth or the more visible areas of the teeth.

As with most dental restorations, composite fillings are not permanent and may someday have to be replaced. They are very durable and will last many years, giving you a long-lasting, beautiful smile.

Who Needs Dental Fillings?

If your teeth are chipped, cracked or damaged by tooth decay, they need fillings. Large cavities are obvious and often painful, but small pinhole cavities and hard-to-see areas between teeth may also need attention. Your dentist can find cavities and sites of tooth decay that you may not see in the mirror. X-rays, dental probes, and dyes can reveal areas that need dental restoration. Your dentist can also see areas that you may not be able to spot, which is one reason why regular dental check-ups are vital for your oral health. Regular visits allow the dentist to see small problems before they become large ones.

Although cavities are the most common reason for fillings, they are not the only reason your dentist may recommend reconstructive work. If you grind your teeth, bite your nails or use your teeth as tools, you may erode the chewing surfaces enough to require a filling to restore a healthy bite.

Signs that you may need a filling include:

  • Visible holes or dark spots on teeth
  • Visible chips or cracks
  • Sensitivity to heat and cold
  • Sharp pain when biting down on the affected tooth
  • A constant dull pain or ache

Materials for Fillings

Fillings used to be made of precious metals because they could withstand years of use. Today, gold and silver amalgam fillings are still available, but new options include tooth-colored resin composites, porcelain and glass ionomer cement. Your dentist will recommend a filling type for you based on the amount of restoration that must be done, the location of the filling, your personal preferences and your budget.

Silver amalgam fillings have the greatest longevity, often lasting 10 years or longer with normal maintenance. Although gold is the more expensive option for precious metal fillings, it offers extraordinarily long wear; gold fillings can last decades or even a lifetime. Silver amalgam fillings contain silver, tin, copper, and mercury. They are an inexpensive option and are most often used to fill small cavities.

Composite resin fillings resemble a specialized epoxy and contain particles of silica or ceramics in a polymer matrix. They can be blended to match the color of the surrounding tooth material, making restoration less noticeable than it is with metal fillings. They also spare more of the original tooth during the filling process. However, resin fillings do not have the longevity of metals and may need to be replaced in under 10 years.

How are composite fillings placed?

Composite fillings are usually placed in one appointment. While the tooth is numb, your dentist will remove decay or old filling as necessary. The space will then be thoroughly cleaned and carefully prepared before the new filling is placed. If the decay was near the nerve of the tooth, a special medication will be applied for added protection. The composite filling will then be precisely placed, shaped, and polished, restoring your tooth to its original shape and function.
