All You Need To Know About Teeth Whitening
What Causes Teeth Stains?
Extrinsic (external) Stains
Extrinsic stains occur when the outer layer of the tooth, also known as the enamel, is stained. This may happen because of several factors:
Frequently consuming coloured foods like coffee, tea, cola, or red wine stains your teeth over time.
Nicotine and tar in tobacco stains the necks of your teeth above the gum line, giving them a yellowish-brown colour.
Poor dental hygiene
Accumulated dental plaque and calculus formed on the teeth due to poor dental hygiene can cause discolouration of teeth, which varies between grey, yellow, black or brown.
Fluoride is known to cause teeth discolouration. Excessive usage of fluoride products such as mouthwash, toothpaste, or drinking water with high fluoride content can cause your teeth to be discoloured.
Intrinsic (internal) Stains
Intrinsic staining takes place at the deeper layer of the enamel and the dentin, which is the tissue lying below the enamel. These stains give your teeth a yellowish or greyish hue. Similar to extrinsic stains, there are many factors for this:
Giving certain antibiotics to children whose teeth are still developing can stain their teeth, which will carry into their adult life.
Teeth can be discoloured from the inside out due to bleeding within the tooth itself, which decomposes and forms a blueish-brown stain.
A small number of people who suffer from congenital issues may also have discoloured teeth.
The outer layer of the enamel on our teeth gets eroded when we turn older, exposing the dentin. As the dentin also turns yellow with age, this will cause our teeth to appear stained.
Send us an enquiry if your teeth is stained and you need help removing them.
How can teeth stains be removed?
Extrinsic stains are best removed through routine scaling and polishing, while intrinsic and age-related discolourations can be treated via professionally prescribed teeth whitening procedures.
What teeth whitening treatments does Raffles Dental provide?
In-office whitening and take-home whitening kits are available at Raffles Dental.
In-office Teeth Whitening
You can achieve whiter teeth in our dental surgeon’s office. Each session for in-office teeth whitening will take around an hour.
How is in-office teeth whitening treatment done?
Before the teeth whitening procedure, routine scaling and polishing will be done to maximise contact between your teeth and the whitening gel**.
The dentist will apply the whitening gel onto your teeth, which is then “activated” by laser light.
Multiple sessions may be required, depending on the state of discolourisation of your teeth.
Take-home Teeth Whitening Kit
An alternative to teeth whitening in a dental office, take-home whitening kits may be a more convenient option for some. Compared to in-office teeth whitening, results for this are more gradual, which can be seen after a few weeks.
How do take-home teeth whitening kits work?
Dental impressions will be taken to create customised trays for your teeth during your first visit.
At the second visit, the trays, together with syringes of bleaching gels prescribed by the doctor, will be given to you.
Depending on your teeth’s condition and the bleaching gel’s concentration, you will be required to bleach your teeth between 20 minutes to 2 hours each day.
Some side effects may also occur from teeth whitening:
This can be managed with sensitivity toothpaste and professional topical fluoride applications.
As the whitening gel is caustic, they can irritate soft oral tissues like the gums, lips or tongue.
If you are unsure which option is suitable for you, make an appointment online or contact a dental clinic near you to consult a dentist.
