What Causes Teeth Stains

Extrinsic (external) Stains

Food Stain

Extrinsic stains occur when the outer layer of the tooth, also known as the enamel, is stained. This may happen because of several factors:

  • 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 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.
  • 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 (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:

  • 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.

Age-related Factors

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.

Treatment Options

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.

The following teeth whitening services are available at Raffles Dental to suit your needs:

In-office Whitening

In-office Whitening at $950.20*

Achieve whiter teeth in our dental surgeon’s office. Each session will take around an hour.

  • 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.
  • Multiple sessions may be required, depending on the state of discolourisation of your teeth.

Take-home Whitening Kit

Take-home Whitening Kit at $400.20*

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.

  • 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:

  • 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, send us an enquiry for advice.
