Nowadays, there is a tremendous degree of public awareness regarding the importance of dental Smile Makeover Dentist. Aside from cavities and other dental concerns, tooth whitening, often known as bleaching, has recently increased in popularity among the general public. It has been reported that dentists who undertake tooth bleaching and whitening operations are in high demand, with 87 percent of those surveyed reporting that they have a high level of demand.
What causes teeth to be white in the first place?
Our teeth Smile Makeover Dentist are made up of various layers, which are as follows: Both hard and protective outside layers, the outermost of which is known as enamel, and the inner part, known as dentin, are present in addition to the soft tissue that makes up the inside of the tooth.
The enamel of a tooth is the hardest layer of the tooth, and the chemical composition of the enamel determines its hardness. Enamel, like our bones, is composed primarily of calcium hydroxyapatite, which is a mineral compound. The mineral hydroxyapatite is naturally white in its native state, which explains why our teeth are so white.
Although our teeth remain white for a long time, the whiteness of our teeth diminishes with age, wear and tear, and the ingestion of coloured substances such as tea, coffee, wine, and cigarettes, and they begin to seem yellowish in colour.
The different types of stains and their classifications
The coloured substances that we see as stains are primarily chromophores, which are light-sensitive molecules. The colour of these chromophores is usually yellowish or brownish in appearance. “Intrinsic” stains can be distinguished from “extrinsic” stains.
Extrinsic stains are those that are visible on the surface of the enamel and are not caused by the enamel itself. Tea and coffee, for example, have the same colour as the chromophore and are referred to as direct stains because of their similar coloration. Other compounds are colourless, but when they come into contact with the enamel, they discolour the teeth due to chemical reactions. Indirect staining is the term used to describe this process. The use of chlorhexidine-containing mouthwashes is a notable illustration of this. Gingivitis can be prevented by using mouthwashes containing chlorhexidine, which is an antibiotic. However, the chemical also stains the teeth, making them appear yellow.
The vast majority of extrinsic stains can be eliminated mechanically with brushing or chemically with bleaching or whitening techniques, depending on the situation. In addition, foods that stain your teeth, such as tea and coffee, should be avoided.
Intrinsic stains are those that originate from within the tooth sensitive teeth treatment, either from the enamel or from the dentin beneath the enamel.
Internal staining can develop prior to tooth Smile Makeover Dentist emergence into the oral cavity in some situations, causing the teeth to appear discoloured. There are a variety of causes that can contribute to this early staining, including some metabolic abnormalities, the use of broad-spectrum antibiotics like as tetracycline, and the absorption of excessive fluoride (fluorosis) during the formative phases of tooth formation.
Large silver fillings, which were routinely used before contemporary tooth-colored fillings became available, or trauma to the tooth are the most prevalent causes of intrinsic stains that arise after teeth have emerged.
When a tooth is injured, this is referred to as dental trauma. Consider the following scenario: your younger brother or sister punched you in the face, and while it hurt at the moment, you forgot about it a few days later. But after a few years, you may notice that one or two teeth appear to be a different hue from the rest of your teeth. Blood leaking into the inner layer of dentin as a result of the trauma (the punch) stained the tooth from the inside out, causing it to discolour.
Intrinsic stains, on the other hand, are significantly more difficult to remove and frequently need the use of invasive techniques.
Various sorts of tooth whitening techniques are available
Dental whitening has been practised for hundreds of years and is not a recent occurrence. When it came to the Egyptians, white teeth were a status symbol, and because they did not have access to our current sophistication of teeth whitening methods when they lived around 4000 B.C., they whitened their teeth using twigs and vinegar instead. Ancient Romans utilised urine to clean their teeth as well as their teeth! The idea was that the ammonia in urine would bleach the teeth. However, this proved to be false. Because of advances in technology, we now have a variety of sophisticated delivery systems as well as scientifically proven chemicals that may be utilised to efficiently whiten teeth.
The most common whitening product is whitening toothpaste, which is available at most drug stores. There is a larger concentration of abrasive component in these toothpastes, which aids in the elimination of stains from the teeth. Despite the fact that such toothpastes can remove surface stains, they do not result in a major alteration in the colour of one’s teeth.
Another whitening product that is often used is mouthwash that contains hydrogen peroxide. When it comes to whitening teeth, they are more effective than whitening toothpastes. They must be used on a regular basis for approximately 3 months before any noticeable shade difference can be seen.
Whitening gels and strips are the most effective of the commercially available whitening products, and they are also the most expensive. In addition to drugstores, tray whitening systems are more typically provided in dental clinics, with instructions on how to load the trays with bleaching materials and how long you should use/wear them for. Tray whitening systems are also accessible online.
Teeth whitening or bleaching treatments performed in the dental office are the only ones available. Chemical bleaching is the term used to describe this process. Because it has a higher concentration of bleaching chemicals than over-the-counter whitening solutions, the results are more obvious; however, the cost may be more as a result of the increased concentration.
The science and technology of chemical bleaching
Tooth stains, also known as chromogens, are dark-colored chemicals that are present in the mouth. In contrast to extrinsic stains, which are formed by chromogens that contain conjugated double bonds, intrinsic stains are caused by chromogens that contain metal atoms in their chemical structure.
Peroxides, such as hydrogen peroxide and carbamide peroxide, are among the most commonly used bleaching agents. It is produced when carbamide peroxide comes into contact with water, which is known as hydrogen peroxide formation.
Bleaching is simply an oxidation reaction in which bleach (hydrogen peroxide) oxidises the double bond in tooth stains (chromogen), causing the chromogen’s chemical structure to alter. Bleaching is used to remove stains from teeth. Consequently, it becomes a lighter-colored compound with a greater whitening impact as a result of this transformation.
If you have intrinsic stains caused by chromogens and metallic compounds, veneers or crowns can be used to whiten your teeth more effectively than chemical bleach.
Is there a drawback to using chemical bleaching methods?
If the bleaching substance comes into touch with your gums or tongue, it has the potential to cause soft tissue burns to your mouth. While antiseptic ointments can help to alleviate the symptoms of a burn of this nature, considerable caution must be exercised when working with bleaching agents. If bleaching agents are mistakenly swallowed, they may produce minor stomach upset, but fortunately, the little concentration is not known to have a substantial effect on us.
The most significant consequence is the way that bleach damages the tooth enamel. It has been demonstrated that aggressive bleaching increases the surface roughness of enamel and causes it to become demineralized. Teeth become porous as a result of this, resulting in increased sensitivity. After undergoing a bleaching procedure, it is vital to understand that one may suffer greater sensitivity to light. In fact, those who have previously had cavities filled and then bleached their teeth are more likely to be affected by this condition than other individuals.
Nobody wants yellow teeth Dentist in Lahore, and we all know that no one wants to have them, but that doesn’t mean you should rush out and get a bleaching procedure every month. After all, it is a chemical process, and while it is unlikely to have significant side effects, it is possible that it will have a few unfavourable impacts. To be on the safe side, it’s best to bleach your teeth at a dental clinic under the observation and control of an experienced dental practitioner, with a two-week interval between bleaching sessions. By following this fundamental guideline, you will reduce the hazards related with bleaching because you will be advised by an expert!
