3 Signs You May Need A Root Canal

A root canal is a procedure that protects a compromised tooth against further injury or decay by the removal of the living tissue, or pulp, within the tooth. The resulting empty chamber is filled with a special type of latex, and the tooth is capped by a realistic-looking crown that preserves the ability to bite and chew. Although the decision about whether a root canal is necessary should be made by a dentist, it is important to be aware of these common signs that indicate dental distress:


  1. Tooth Fracture

An injury that breaks or chips a tooth may have exposed its inner pulp chamber, leaving it vulnerable to infection. Seeking dental care immediately after trauma to the mouth can help prevent further damage to the blood vessels and nerves in the affected tooth, as a dentist can sanitize the wound and provide the necessary restorative work to seal the pulp chamber. However, a root canal may be the optimal solution for a tooth that has suffered extensive injury.


  1. Extreme Sensitivity or Pain

If a particular tooth hurts when it is touched or is especially sensitive to temperature extremes, the underlying nerve may be inflamed. Although this condition does not always necessitate a root canal, it should be evaluated by a dentist in order to rule out the possibility of an infection that could otherwise lead to the eventual loss of the tooth.


  1. Localized Swelling

An infection within the pulp chamber of a tooth may lead to swelling of the gums around the affected tooth. There may also be foul-tasting liquid draining from the area. In order to prevent serious infection of the jawbone, face, or blood, such an abscess must be treated as quickly as possible by a dentist.

Watch This Video to Learn More About Periodontal Disease

Periodontal disease is a common condition that results from improper oral care. The detailed animation in this video provides a close-up look at the stages and consequences of periodontal disease.

Healthy gums, or gingiva, do not bleed or hurt during a dental exam and are strongly connected to the teeth. However, when tartar builds up on the teeth, the gums become inflamed and bleed easily—two major symptoms of gingivitis. Fortunately, this condition is easily treatable, unlike periodontitis, which involves the destruction of connective dental tissue and may result in devastating complications such as tooth loss, atherosclerosis, and heart disease.

Maintaining Your Teeth After Whitening

Taking good care of your smile is something to be proud of, which is why many people highlight their healthy teeth with a professional whitening treatment. To get the best results, remember to do the following after whitening your teeth:

Avoid Foods and Beverages that Stain Teeth

Many daily habits—such as having a morning cup of coffee, eating a snack of chocolate or berries, or relaxing with an evening glass of wine—can quickly stain teeth, negating your whitening efforts. Try to limit dark-colored foods, and rinse your mouth or brush your teeth afterward if you do indulge. Drinking soda, tea, and coffee through a straw will also help you keep your front teeth glistening white.

Practice Good Oral Hygiene

Brushing at least twice each day removes stain-causing compounds before they have a chance to permeate your teeth, and flossing daily minimizes your risk of tartar buildup. Every few days, switch to a whitening toothpaste to scrub away any discoloration that has begun to accumulate.  

Abstain from Tobacco Use

Among the many other reasons to stop using tobacco are the ugly brown stains it leaves on teeth. For this reason, having your smile professionally whitened can be great motivation to quit smoking or chewing tobacco, as you want your results to last as long as possible.

Schedule Whitening Touch-Ups

Even if you take care to follow the above guidelines, your teeth will still become dull over time, which is why occasional whitening touch-ups are recommended. A dentist can help you determine how often you should undergo such treatments in order to maintain the smile you desire.
