Teeth Whitening

Professional dental whitening procedures are excellent in achieving a quick and effective solution. Various home teeth whitening products are also available if you’re looking for a more affordable and convenient option. Let’s explore what teeth whitening is, who it’s suitable for, the different types of teeth whitening, the steps involved, and how to take care of your teeth afterward.

What is Teeth Whitening?


Teeth whitening, also known as teeth bleaching, refers to various cosmetic dental procedures that aim to enhance the brightness and whiteness of natural teeth. This process involves removing stains and discoloration from teeth using a bleaching agent, such as hydrogen peroxide, carbamide peroxide, or sodium perborate. 


Indications of Teeth Whitening


Teeth whitening is an effective option for removing colored stains caused by foods and drinks, such as coffee or red wine, smoking, or some amalgams. It is indicated in the following:


Yellow teeth- caused by aging or teeth that have erupted with coloration due to a tetracycline treatment during their development (tetracycline should not be administered to children!).


Dental fluorosis: Teeth whitening can also improve the appearance of teeth affected by some types of fluorosis (excess fluoride during the development of the teeth). 


After endodontic treatment- In some cases, teeth may have changes inside, such as the death of the nerve or root canal treatment, that can result in discoloration. Teeth whitening may also suit these cases, but your dentist must evaluate the situation to determine the best course of action.


Types of Teeth Whitening


In-office whitening- This is the most common type of teeth whitening in a dentist’s office. Your dentist will apply a teeth-whitening gel and use a special light or laser to activate the whitening agent. This type of whitening can typically be completed in one session.


At-home whitening- This type involves using a kit your dentist provides. The kit typically includes custom-made trays that you wear over your teeth and a whitening gel. You’ll need to wear the trays for a specified amount each day for several weeks to achieve the desired level of whitening.


Over-the-counter whitening products– include whitening strips, gels, and toothpaste. While they are less expensive than professional whitening, they may be less effective and can cause tooth sensitivity.


How is the Teeth-whitening procedure carried out?


If you decide to go ahead with teeth whitening, here are the steps you can expect:


1. Your dentist will examine your teeth to decide whether you qualify for the procedure. This may involve taking x-rays to check the health of your teeth.

2. If you do the procedure in a dentist’s office, your dentist will prepare your teeth by protecting your gums and lips with a special shield.

3. If you’re using a home whitening kit, your dentist will take impressions of your teeth for the tray/mouthguard that will be needed.


The whitening process involves applying the bleaching agent to your teeth and leaving it on for a specified time. In-office whitening is typically done in one session, whereas home kits require consistent use for 30 minutes to an hour over two to four weeks. During this time, you’ll need to prepare the trays and apply the whitening agent according to the instructions.


Once the whitening process is complete, your dentist will rinse your teeth to remove the bleaching agent. If necessary, the process may be repeated to achieve the desired level of whitening. 


Care after Teeth whitening


After teeth whitening, taking care of your teeth is essential to maintain the results. Here are some tips:


Avoid staining beverages and foods: To prevent new stains, avoid drinking coffee, tea, red wine, and other dark-colored beverages. It would help to stop tomato sauce and berries that stain your teeth.


Brush and floss regularly: Maintaining white teeth requires good oral hygiene. Brush your teeth twice daily and at least floss once daily to remove plaque and prevent stains from forming.


Use whitening toothpaste: Whitening toothpaste can help maintain teeth whitening results. Look for toothpaste that contains fluoride and a gentle whitening agent, such as baking soda or hydrogen peroxide.


Schedule regular dental cleanings: Regular dental cleanings can help to remove surface stains and prevent plaque buildup, which can dull your teeth. Your dentist may also recommend touch-up whitening treatments to maintain your results.


Be mindful of sensitivity: Teeth whitening can sometimes cause temporary sensitivity or discomfort. If you experience sensitivity, avoid hot or cold drinks.
