If we think about what attracts us to a person in general, the first thing that we can think of is a great, warm smile. A good set of well-aligned white teeth is an important aspect of this great smile. However, white teeth remain an elusive thing for most of us. Some of the common reasons for discoloured teeth are as below.
The degree of discolouration varies widely and also is hereditary. Whatever the reasons, there is the option of tooth whitening, which is effective with optimal oral health and good oral hygiene habits. Tooth whitening is not for everybody though, the following are the definite contraindications.
While choosing to go for tooth whitening, one thing to bear in mind is that it is not a permanent solution to discoloured teeth and might require repetition of the treatment. Having a detailed discussion will help set realistic expectations and achieve optimal results.
Munching foods like apples, pears, carrots or celery after brushing can help in preventing discoloration as they trigger tooth-bathing saliva which helps in keeping the teeth whiter.
A very interesting thing, that most people would have noticed during their visit to the clinic is the white light that is used on the teeth. This is laser light, which is used extensively over the last couple of decades in dentistry for a variety of treatments. The following are some procedures where laser is commonly used.
Caries: In some cases, laser light is used to remove the decayed portion of the tooth and shape the surrounding healthy tooth to receive the restorative material.
Restorations: When composite resins are used to fill the space left by tooth decay, the decayed portion is removed and the enamel etched to improve adhesion. The composite material is then filled in the tooth space to achieve the desired shape and then light-cured.
Veneers: Where a thin layer of the existing tooth is removed to provide a whiter tooth, then laser light is used. These chemicals are inactive and only become activated when exposed to laser light. In cases of both restorations and veneers, one big advantage is it gives sufficient working time for the dentist to shape the material to the desired form and then activate it.
Gingivitis: Laser is also used in gum diseases where bacteria are removed and the gums are reshaped. Using laser on the root surfaces ensures better removal of the hardened calculus and promotes gum reattachment of the gums to the tooth surfaces.
Soft tissue biopsy or lesion removal: Biopsies of the lips, gums, and tongue can be done using laser light. If the lesions are too small and require removal, it can be done by laser, thereby avoiding the need for surgery
Results: In all the above procedures, the laser is more effective than the conventional method that it is replacing. Some advantages include:
Anesthesia not required
Avoids tooth drilling in some cases of very minor decay, so the patient is at ease
Reduces the amount of tooth removal during cavity preparation
Not all situations can be managed with a laser treatment though and conventional biopsies and drills will be required in some cases. As with all other dental situations, a detailed discussion with the dentist on the pros and cons and the patient condition will help make an informed decision.
