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:
Intrinsic (internal) Stains
- Diet. Frequently consuming coloured foods like coffee, tea, cola or red wine stains your teeth over time.
- Smoking. Nicotine and tar in tobacco stains the necks of the teeth above the gumline, giving the teeth a yellowish-brown colour.
- Poor dental hygiene. Accumulated dental plaque and calculus formed on the teeth due to poor dental hygiene can turn coloured, which varies between grey, yellow, black or brown.
- Environmental factors. 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 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 also many causes for this:
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 our teeth appear stained.
- Antibiotics. Giving certain antibiotics to children whose teeth are still developing can stain their teeth, which will carry into their adult life.
- Dental trauma. Teeth can be discoloured from the inside out due to bleeding within the tooth itself, which decomposes and forms a blueish-brown stain.
- Genetic factors. A small number of people who suffer from congenital issues may also have discoloured teeth.
Extrinsic stains are best removed through routine scaling and polishing, while intrinsic and age-related discolourations can be treated via professionally prescribed tooth whitening procedures.
Raffles Dental offers a range of services to suit your needs:
In-office Tooth Whitening
People who wish to see fast results may prefer this option, as your teeth may turn noticeably whiter after a single session.
- Before the 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.
Take Home Bleaching Kits
An alternative to teeth whitening in a dental office, take home bleaching kits may be a more convenient option. Compared to in-office teeth whitening, results for this are more gradual, which can be seen after a few weeks.
- Multiple sessions may be required, depending on the state of discolourisation of your teeth.
- 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 the teeth between 20 minutes to 2 hours each day.
Do take note that some side effects may also occur from the teeth whitening:
- Tooth sensitivity. This can be managed with sensitivity toothpaste and professional topical fluoride applications.
- Oral Irritation. 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, drop us an enquiry for advice.
