Have you ever wondered why some people’s teeth seem to be more yellow or darker in colour when compared to others? Do you find that your teeth have changed colour over time?
There are several common reasons for teeth to be darker or change in colour which include:
NATURAL STRUCTURE OF TEETH
The outer layer of teeth (enamel) is usually more translucent and whiter in colour, whereas the deeper layer (dentine) is naturally more yellow or darker in appearance.
AGE
With increasing age, the outer ‘enamel’ surface of the teeth tends to wear down, resulting in the teeth losing some of its white appearance. In addition, the deeper ‘dentine’ layer may become thicker or more prominent, resulting in the teeth taking on a more yellow appearance.
WEAR & TEAR
As teeth continue to ‘wear and tear’ over time eg. Normal chewing/biting, acid erosion, teeth grinding or clenching habits etc. the white ‘enamel’ surface can wear away, thereby exposing the more yellow ‘dentine’ layer beneath.
DEVELOPMENTAL ISSUES
Teeth are easily susceptible to environmental and external factors during their growth and development. Certain medications eg. Tetraycline antibiotics etc. as well as on-going background situations eg. Prolonged medical issues etc. may result in the developing teeth taking on a darker or altered appearance.
GENETICS
Our genetics may also play a role in the appearance and colour of our teeth. In some families there can be strong genetic traits which influence the colour or shape of our teeth, which can be passed down from either side of our parents.
TRAUMA
In certain instances where there is significant injury to ‘baby’ teeth eg sports injury, a fall etc. then it can affect the shape and appearance of the ‘developing’ adult teeth which is underneath.
In fully formed ‘adult’ teeth where a significant impact has been sustained eg. Trauma, physical injury etc. then the nerve may lose its sensation, with the tooth subsequently turning darker in colour.
TOOTH DECAY
When tooth decay develops beyond a certain stage the affected area can take on a brown-black appearance. If the decay ends up extending to the nerve, then the tooth may eventually turn darker in colour.
ROOT CANAL TREATMENT
After a tooth has had root canal treatment it may develop a darker appearance over time. This can take place several weeks-months-years after the initial root canal was completed.
DIET
Teeth can become stained after exposure to dark coloured food and drinks eg. Tea, coffee, red wine, sauces etc. Even though one may brush their teeth regularly some of these stains are quite stubborn and attach to the surfaces of teeth over time.
PLAQUE & CALCULUS BUILD-UP
Over time the build-up of food, bacteria, plaque and calculus can result in discolouration of the teeth. If this build-up accumulates for too long a period, then it may become stubbornly attached to the teeth and difficult to remove through normal brushing habits.
CONCLUSION
As you can see there are several different instances why teeth can have a more yellow or darker appearance. Depending on the cause it may be part of the natural development of the teeth, or indicative of another reason that may require some form of treatment.
If you believe that your teeth have a more yellow or darker appearance and want to check if it is due to natural changes or indicative of underlying issues, then it is advisable to see your local dentist for an examination. The dentist can assess the appearance of your teeth and discuss with you if there is any management that is required.
