Teeth bleaching: 4 ways to bleach teeth

Tên quảng cáo

Teeth bleaching is one of the most popular cosmetic procedures. Enamel’s natural light ivory color can fade to yellow, orange, brown, gray, and even blue or green. Stains from coffee or tobacco, injury that has damaged the pulp, ingestion of the antibiotic tetracycline or high levels of fluoride while the teeth are developing, corrosion from silver fillings, and natural wear away of the enamel with age are all causes of discoloration.

Although bleaching can successfully remove many stains, it can be painful for people who have sensitive teeth or an exposed root. Several different bleaching methods can be utilized.

Why do we need teeth bleaching?

Almost everyone loves to have a bright, healthy smile. Your teeth may darken due to a variety of factors. Some circumstances are beyond our control, such as age or childhood accidents that may alter the production of our tooth enamel. As a result, it’s important to discuss any plans for teeth whitening with your dentist.

Your dentist can determine if the stains on your teeth are the result of a lifestyle factor, such as frequent coffee intake, or whether there is a more serious oral health issue at work. Despite the fact that bleaching is usually done for cosmetic reasons, your dentist may be able to advise you on the best course of action for your specific stains. The good news is that dental stains may often be removed. That justifies working toward a radiant white grin.

Tooth discoloration can be caused by surface stains on the tooth’s surface, real changes in the tooth’s composition, or a combination of the two. According to orthodontists, there are three forms of tooth discoloration:

  • Extrinsic Teeth Stains:

The most common type of tooth discoloration is extrinsic tooth darkening. It occurs as a result of exposing teeth to stains such as:

  • Tar and other chemicals are found in cigarette smoke.
  • Foods that stain, including chocolate, berries, and others
  • Liquids that are dark in hue, including coffee, black tea, colorful sodas, red wine, and dark beer

Despite the fact that many meals that induce tooth discoloration are black in color, not all of them are. Apples and potatoes, even if they are light in color, can discolor teeth.

  • Intrinsic Teeth Stains:

Numerous internal dental changes can cause intrinsic tooth discolouration. Chemical or physical changes to the tooth might be the cause of intrinsic tooth discolouration. Physically, as we age, our dental enamel deteriorates, exposing the dentin, the inner structure of the tooth. Individual variances in dentin color can cause teeth to be yellowish, brown, or gray in color.

Dental trauma can also cause tooth discolouration. When the pulp of a tooth dies, the tooth may turn dark or even black. Damage to the tooth before it emerges may also occur, resulting in insufficient enamel formation and a discolored region on the tooth. Tooth decay can also discolor your teeth.

Some drugs and chemicals, such as tetracycline or too much fluoride in childhood, can produce enamel defects that manifest as tooth discolouration.

Because intrinsic tooth discolouration does not react well to teeth whitening, the best option to treat it is with porcelain veneers or other treatments that cover the discolored tooth enamel.

  • Age-Related Teeth Stains:

Age-related teeth stains combine the impacts of intrinsic and extrinsic tooth discoloration. Teeth darken with age because dentin, the core component of the tooth, naturally ages. The dentin becomes increasingly visible when the tooth’s enamel thins with age. The majority of people’s teeth will yellow with age owing to these natural causes of discoloration as well as extrinsic ones such as the impact of certain foods, beverages, and smoking.

Chair-side teeth bleaching

Your dentist will use an acid solution to clean your teeth before applying an oxidizing agent to the enamel. To accelerate the lightening process, your teeth are exposed to a bright light or a laser. To achieve the desired color, three to four sessions of 30-60 minutes each are usually required. Power bleaching is a newer technique that uses a highly concentrated form of hydrogen peroxide as the lightening agent. It can produce results in a single session.

However, bleaching is only temporary. Within one to three years, your teeth will darken again, and you may need to repeat the procedure. Some dentists charge between $75 and $225 per session, while others charge a single fee of $300 or more.

Home teeth bleaching (dentist prescribed)

Your dentist will create a mouthpiece that is custom-fit to hold the bleaching chemicals (carbamide peroxide or hydrogen peroxide). The bleaching is then done at home by spreading the chemicals into the mouthpiece and wearing it for the recommended amount of time (between 30 minutes and several hours) each day for a week or two. This procedure is typically priced between $200 and $600.

Bleaching pulp-damaged teeth

When the pulp is dead or injured, the tooth will discolor. To address this issue, your dentist can use a bleaching agent to rinse the pulp chamber while conducting root canal treatment. If the stain returns or the tooth darkens after the root canal, your dentist can reopen the pulp chamber and fill it with bleach for several minutes under a heat lamp.

This procedure may need to be repeated multiple times. Alternatively, the dentist can place a temporary filling in the pulp chamber and fill it with a bleaching solution. You’ll need to return in a few days to have the bleach removed and the tooth permanently sealed. Costs vary depending on the practice; some charge between $300 and $400 per tooth.

Over-the-counter teeth bleaching kits

These kits work in the same way as professional products. You start with an acid rinse, then a hydrogen peroxide gel, and finally a whitening pigment is applied to the tooth. Many over-the-counter tooth whitening strips and kits range in price from $15 to $40.

Many consumers opt for this bleaching method because it is less expensive than other techniques, But good results cannot be ensured. Without professional diagnosis, it’s hard to determine the source of discoloration and the effectiveness of the bleaching agent.
