The tooth is made of 3 layers, each with unique characteristics and specific function, the enamel, dentin, and pulp. The enamel is the outermost layer of the tooth and gives the tooth it's hard and lustrous appearance. The enamel is thicker on the crown than the root and is the first one to be affected by tooth decay. The only symptom when the enamel is decayed is food lodgment and discoloration.

The dentin is the next layer, which is composed of minute fine tubules leading from the enamel to the living portion of the tooth, which is the pulp. Once decay progresses from the enamel, the dentin is affected, and this leads to sensitivity in the teeth. When the root portion is exposed to the oral environment, because the root is covered by a more delicate substance called cementum, more severe dental sensitivity ensues.

There is a sharp, shooting discomfort through the tooth to specific foods, such as sweet, acidic, or hot or cold foods.  The main reasons for tooth sensitivity include:

• Tooth decay, both crown and root caries
• Periodontal disease and gum recession
• Tooth erosion 
• Aggressive tooth brushing
• Mouth breathing
• Bruxism or night grinding 

However, there are some simple ways to manage sensitivity, which can be done regularly at home.

1. Toothpaste made for sensitive teeth: Potassium nitrate has been shown to block the tubules and has been included as an active ingredient in toothpastes. These are very effective, and if you are brushing twice, this can be used instead of the regular paste once.
2. Brushing: Both the type of toothbrush and the brushing technique can have an impact on sensitivity.  Change to softer brushes and learn the ideal way to brush your teeth. A lot of times, rough brushing can lead to erosion and subsequent sensitivity
3. Rinsing: Fluoride containing rinses have been proven to reduce sensitivity 
4. Food habits: Even before sensitivity sets in, being cautious to avoid acidic fruits and juices can help prolong the onset of sensitivity. If possible, consuming these food stuffs should be followed by brushing or at the least a thorough rinsing
5. Sealants: If a person is prone to caries (deep pits and fissures, for instance), then it is advisable to get sealants applied on the teeth. This can reduce the instance of wearing of the enamel which then leads to sensitivity
6. Mouth guard: If you are a night grinder, then a mouth guard can help curtail this habit and thereby reduce sensitivity.

There you go with how to reduce sensitivity. Try these simple, easy measures and go on to enjoy the sweets or hot or cold foods that you have always craved for.

Problems with the skin during the teenage years are very common. Although skin issues can be really stressful, the right skin care treatment can help in controlling the problems you may face during this time. Here are some of the skin issues that you may face at this stage of life and ways to prevent them:

Oily Skin: Oily skin is a very common occurrence during teenage years. To a certain extent, oily skin may be due to genetics but for some, it may be due to hormonal changes that cause excess oil to be produced on the skin surface. In order to not inflame the skin further, individuals with oily skin shouldn't overly scrub their skin as well as not use harsh cleansers to clean the face. More importantly, when you do use a cleanser on your face, you should only do so two times a day. If you go overboard, it would only do more harm than good.

Acne: Whether it is blackheads, whiteheads or spots filled with pus, acne affects about 80% of teenagers at some point in their lives. Teenagers are more prone to this problem because the hormone levels during this time are especially high, resulting in an increase in the magnitude of sebaceous glands and the oil that is produced. When too much oil is produced, this, along with dead skin cells block, the follicles, giving rise to acne. There are certain ways in which you can prevent it from occurring, such as always having a bath after any strenuous activity, not picking or touching the problem areas and washing acne-prone spots only two times a day.

Excessive Sweating: Excessive sweating is another major cause of concern for teenagers. The problem can be due to two different conditions - stress or hyperhidrosis (a condition wherein you sweat excessively on a daily basis). Wearing clothes made from cotton, using antiperspirants as well as avoiding drinks and foods that may cause episodes of excessive sweating are some of the ways in which you can keep the problem in control.
