Teeth discoloration is a common problem faced by many. stain from food is the most common cause of teeth discolouration. Apart from this, sodas, and aerated cold drinks can harm the enamel and make it more prone to discolouration. Teeth whitening products like toothpastes or home remedies can also do more harm than good . Such products usually work by removing the layer of your enamel which can lead to tooth sensitivity. Therefore, it is recommended that if you want a million dollar bright white smile, it should be done under the supervision of a Dentist at the dental clinic.
Over time, your teeth can go from white to not-so-bright for a number of reasons:
Food and Drink
Coffee, tea and red wine are some major staining culprits. What do they have in common? Intense color pigments called chromogens that attach to the white, outer part of your tooth (enamel).
Two chemicals found in tobacco create stubborn stains: Tar and nicotine. Tar is naturally dark. Nicotine is colorless until it’s mixed with oxygen. Then, it turns into a yellowish, surface-staining substance.
Below the hard, white outer shell of your teeth (enamel) is a softer area called dentin. Over time, the outer enamel layer gets thinner with brushing and more of the yellowish dentin shows through.
If you’ve been hit in the mouth, your tooth may change color because it reacts to an injury by laying down more dentin, which is a darker layer under the enamel.
Tooth darkening can be a side effect of certain antihistamines, antipsychotics and high blood pressure medications. Young children who are exposed to antibiotics like tetracycline and doxycycline when their teeth are forming (either in the womb or as a baby) may have discoloration of their adult teeth later in life.
This procedure is called chairside bleaching and usually requires only one or two office visits. our dentist will apply either a protective gel to your gums or a rubber shield to protect your gums. Bleach is then applied to the teeth.
we can provide you with a custom-made tray for at-home whitening. In this case, we will give you instructions on how to place the bleaching solution in the tray and for what length of time. This may be a preferred option if you feel more comfortable whitening in your own home at a slower pace, but still with the guidance of our dentist. Out-of-office bleaching can take anywhere from a few days to a few weeks.
Some people who use teeth whiteners may experience tooth sensitivity. That happens when the peroxide in the whitener gets through the enamel to the soft layer of dentin and irritates the nerve of your tooth. In most cases the sensitivity is temporary. You can delay treatment, then try again.
Overuse of whiteners can also damage the tooth enamel or gums, so be sure to follow directions and talk to your dentist.
