Tooth Decay (Cavities/ Caries)
What is Tooth decay?
Tooth decay in short is nothing but destruction of the tooth enamel. Foods containing carbohydrates/ sugars / starches such as milk, pop, raisins, cakes or candy if left on the teeth result in tooth decay. Bacteria living in the mouth react with these foods thereby producing acids. Acids erode the enamel on your tooth thereby causing tooth decay over a period of time.
What are the symptoms and signs of Tooth decay?
Tooth decay, if it is in the beginning stages, hardly shows any symptoms. Otherwise, depending on the location of the cavity as well as its severity it might show the following signs and symptoms
1.Tooth pain/ ache
2.Pus around the tooth
3.Sensitivity of tooth
4.Difficulties in eating/ chewing sweet, hot or cold items or biting
5.Holes or pits visible in your teeth
6.Unpleasant mouth smell
What causes Tooth decay?
Tooth decay is mainly caused by the extent of fermentable carbohydrates viz. sugars and starches from the diet and their reaction with the plaque from your mouth. The foods you eat and the liquid you drink contain fermentable carbohydrates and the plaque bacteria in your mouth feed on them thereby converting them to acid. This acid is capable of dissolving the enamel thereby causing a cavity in your tooth. Over a period of time this cavity gets deeper and deeper and reaches the dentine which is the calcareous part of your tooth. As the cavity spreads through the dentine the support for the enamel reduces and the enamel become brittle and breaks. At this stage you will experience severe pain. If you do not treat this on time the dental decay might spread to the pulp and if the pulp gets infected an abscess will be formed.
The tooth decay does not take place in a short period and it takes a long time. Saliva also is useful in washing off some of the bacteria and acid. However, the process accelerates once each layer gets eroded by the decay. Normally the back teeth viz. the molars and premolars are the most affected by tooth decay because they have a number of grooves, pits and crannies to chew food and food particles collect in these places. Plaque builds up in this and allows bacteria to thrive. This causes acid formation and erosion of tooth.
What are the stages of Tooth decay?
1.When we eat sugar and starch, plaque produces acid which attacks teeth.
2.Cavity (hole) develops and the acid attacks the dentine.
3.Bacteria attack nerves and blood vessels from soft pulp.
4.Root and socket become infected
What are the negative impacts due to Tooth decay?
People do not take cavities and tooth decay that seriously because it is a common thing. You must understand that these can result in the following problems which might affect not only adults but also children with baby teeth.
2.Abscess in tooth
3.Loss of tooth
5.Problems in chewing
Severe pain due to tooth decay/ cavities might hamper your normal life and you will find yourself absenting from work. Chewing or eating will be painful which might make you avoid your food routine thereby resulting in weight loss or problems of nutrition. Tooth loss might give you an inferiority complex that you might find difficult to overcome. Abscess in tooth could be life threatening if not treated properly.
How do you diagnose Tooth decay?
Your dentist will diagnose tooth decay or cavity by checking on tooth pain, sensitivity, dental X-rays and physical examination of the teeth.
There are three types of tooth decay and these are smooth surface decay, pit and fissure decay and root decay and brief details are as follows.
1.Smooth surface decay – this is decay on the flat surface of a tooth wherein the bacteria is likely to remain for a long period and the resultant acid will dissolve the tooth enamel.
2.Pit and fissure decay – this is decay affecting the pits and grooves on the chewing surface of your back teeth and it deteriorates if your oral hygiene is bad
3.Root decay – this is decay that occurs on the surface over tooth roots and is common in elderly people with receding gums.
Is it possible to reverse the process of Tooth decay?
In the early stages of tooth decay, the loss minerals in the tooth result in small white spots to appear on the tooth. It is possible to reverse this at this stage by brushing twice a day using fluoride toothpaste and also taking measures to improve saliva flow by chewing sugar free gum. Once the breaching of enamel takes place, it is not possible to reverse this process.
How to prevent Tooth decay?
The following actions taken regularly by you will prevent the occurrence of Tooth decay.
1.Brushing teeth with fluoride toothpaste twice a day
2.Rinsing of your mouth with a fluoridated mouth rinse
3.Cleaning between teeth with floss or an interdental cleaner daily
4.Stop eating snacks between meals
5.Have a balanced diet
6.Regular professional cleaning and oral exams
7.Application of dental sealants to the chewing surfaces of the back teeth which are the starting point for tooth decay
How to treat Tooth decay?
The type of treatment for tooth decay and cavities is mainly dependent on the severity of the problem. The following are some of the options that the dentist will recommend:
1.Fluoride treatments – In order to prevent cavities and facilitate the teeth to repair themselves fluoride can be used. If the tooth decay is in the initial stages of development it might be possible to restore the enamel by fluoride treatment. These treatments can be in the form of a liquid solution, a gel, foam or varnish that is brushed onto your teeth.
2.Fillings – In order to replace decayed areas of your teeth the doctor might advise you to go in for fillings in case the decay has gone beyond the stage of fluoride treatments. This is also known as the process of tooth restorations. In this process, the dentist will remove the decayed part of the tooth and then fills this gap with certain fillings to restore the shape of the tooth. The materials used for fillings are tooth-colored composite resins, silver amalgam, porcelain or combinations of several materials.
3.Crowns – If the decay is bad or if the tooth has weakened the dentist might recommend for going in for a crown than a filling to treat your cavity. In this the tooth is covered with a crown after the decayed part is removed. Materials used for the crowns are gold, porcelain or porcelain fused to metal.
4.Root Canal – If the decay reaches the inner material of the tooth you have to go for a root canal treatment wherein the pulp of the tooth is removed and then replaced with a filling.
5.Tooth Extractions – It is always preferable to save a tooth than extract a tooth and this should be your last option. In this the decayed tooth is removed totally. The major disadvantage in extracting the tooth is that the teeth around this tooth will start moving. Hence, you must opt for dental implant if you can afford it.
