Have you desired for whiter teeth in the mirror?

You’re among thousands with teeth staining. A bright, white grin is beautiful and boosts self-confidence. Professional teeth whitening may repair discoloured or yellowed teeth.

Professional Teeth Whitening?

Professional teeth whitening employs high doses of hydrogen or carbamide peroxide to whiten teeth from below. Our skilled dentist oversees the teeth whitening procedure. Professional teeth whitening often takes one to two hours, depending on stains.

Dentists are trained professionals who understand the intricacies of dental anatomy and know how to protect the soft tissues of the mouth, such as the gums and lips, from potential harm. They also have the necessary tools and equipment to isolate the teeth during the whitening procedure, minimising the risk of sensitivity or damage to surrounding tissues.

Tooth Discolouration Causes

Below are a few of the common causes of tooth discolouration:

  • Acidic or dark foods. 
  • Dark foods and drinks stain. 
  • Coffee, tea, soft drinks, and wines. Apples and potatoes may stain teeth.
  • Tobacco usage and nicotine stains teeth over time. 
  • Plaque and discolouration may result from insufficient brushing and flossing.
  • Disease and therapy. Diseases may discolour dental enamel or dentin. 

Why Whiten Your Teeth at the Dentist?


Whiter teeth are beautiful. It also alters your image. Bright pearly whites may make you seem smart and confident.

Look younger

Whiter teeth help you seem younger since ageing alters tooth colour. Dark and acidic chemicals discolour teeth over time. Teeth whitening gives you a youthful glow.

Dramatic outcomes

Two to eight shades lighter after an hour of expert tooth whitening. Home therapies are slower and less effective.

Safety assurance

Tooth whitening might have unwanted consequences if done improperly. Bleaching solution irritates gums over time. Professional treatment greatly reduces danger.

Less tooth sensitivity

Some dental patients experience transient tooth discomfort from regular at-home teeth whitening. A brighter smile may not include sufficient aftercare. Our dentist can track your therapy. Professional teeth whitening produces dramatic results, which deters patients from frequent procedures.

Teeth whitening: how?

In-office whitening uses a high-concentration peroxide gel (15–43% peroxide) for 15-20 minutes. A unique light activates peroxide, speeding up the whitening process. Dental work takes one to two hours.

The dentine, which is somewhat softer than the enamel, absorbs the bleaching gel. It interacts with discolouring compounds. Thus, teeth dentine lightens and appears whiter. Bleach makes enamel surfaces more reflective, making them whiter.

Before starting the aesthetic surgery, your dentist protects your dental tissues. Cheek retractors open mouths and protect lips. A gingival barrier protects your gums from the blue light and peroxide solution. To avoid ingestion, a strong vacuum suction will be applied.

How Many Teeth Whitening Sessions Are Needed?

One annual in-office teeth whitening appointment usually lightens teeth. The bleaching substance is administered in many coats depending on the stain and patient objective, and the teeth are checked between coats. Professional teeth whitening provides the fastest and most dramatic effects.

How Long Do Whitened Teeth Last?

Teeth whitening can last six months to two years. Patients’ lifestyles and aftercare affect it. The following practises will help you maintain treatment whitening:

  1. Stop smoking. Smoking stains teeth most. Smoked or chewed tobacco will discolour.
  2. Avoid coffee, tea, and alcohol. Straws reduce discoloration from these drinks.
  3. Avoid teeth-staining foods. Berries and beetroots are examples.
  4. Maintain dental hygiene. Brushing and flossing prevents oral bacteria buildup. Home dental care may preserve your new dazzling whites.

Keep regular dental visits. Our dentist should inspect your teeth and gums every six months. Because they may be treated immediately, this can avoid major dental issues. Your doctor may also suggest scheduling a touch-up teeth whitening treatment to preserve your beautiful smile.
