Tooth sensitivity is a condition when the nerve ending in the teeth are overly sensitive to hold hot and cold conditions. Drinking and eating hot or cold food may cause a sharp pain in the tooth. A material called dentin, which is what makes up the inside of your tooth, is protected by the enamel in the crown and the cementum in the root of the tooth. In cases when the dentin loses its covering, teeth may be become sensitive.

Causes of sensitive teeth
1. Inflammation caused by bacteria may lead to sensitive teeth.
2. Gum diseases such as gingivitis may cause the gums to retract and reveal the roots of your teeth.
3. Constantly grinding your teeth can cause the enamel to break down, which leads to exposure of the dentin.
4. Accumulation of plaque can cause sensitive teeth.
5. Various acidic foods such as lemon cause the enamel to be worn out.
6. Sensitive teeth is caused by decay of the tooth.
7. Various dental procedures such as teeth restoration and cleaning of the teeth cause the teeth to be sensitive.

Treatments for sensitive teeth
1. You need to use dental products that contain fluoride. Fluoride products tend to decrease teeth sensitivity.
2. Restrict consumption of acidic foods such as lemon and some dairy products.
3. If you grind your teeth then start using mouth guard.
4. Follow proper dental hygiene, such as brushing and flossing on a regular basis to keep teeth sensitivity at bay.
5. You should use a toothbrush that has soft bristles so that the gum tissue is not affected while brushing.
6. You may use a toothpaste that has been made for people who have sensitive teeth.
7. You may apply fluoride varnishes to root surfaces that have been exposed.
8. You may cover up root surfaces with white fillings.
9. Application of dentin sealers to root surfaces that have been exposed may help in preventing tooth sensitivity.
10. Laser is also effective to fix tooth sensitivity.

Though your child's first set of teeth are not permanent, they are still critical to the development of healthy gums, jaws, permanent teeth, and dental hygiene habits. From first teething to the development of permanent adult teeth, you can help your child to develop and maintain strong healthy teeth and gums.

THE FIRST TEETH

The first teeth usually erupt at around 6-8 months beginning with the lower front teeth and working back towards the molars, usually in pairs. A full set of baby teeth usually appears by the age of 2.5 years and remains stable until the age of 5 or 6 when baby teeth begin to be replaced by permanent teeth

TEETHING PAINS

As these first teeth begin to push through the gum, your child may experience teething pain. Redness or rash on the cheeks, increased drooling, restlessness, irritability, and loss of appetite can all be indicators that your child is teething. If however your child also experiences fever, vomiting, or diarrhea you should take them to a physician as these symptoms are often caused by ailments other than teething.

Once you've established that your child is teething, you can ease their pain in a number of ways. Allowing your child to chew on a chilled teething rings or other cold hard objects can help numb the gums and cause the tooth to erupt sooner. Teething gels can also help reduce the pain through numbing and can be found in most pharmacies. Finally, you can also massage your child's gums

with a clean finger, reducing the pain with light pressure on and around the location of the erupting teeth. Teething cookies and other food (or alcohol) based home remedies are not recommended as they may lead to tooth decay caused by food debris left in the gums or new teeth.

Teething can be a trying time for parents and child alike, but it will not last forever and there are several simple effective ways to manage your child's discomfort.

FIRST DENTAL VISIT

As soon as your child has her first teeth you can begin to think about scheduling a first dental appointment. The appointment should be made on or before your child's first birthday. Before the appointment you may wish to bring your child into the dental clinic for a short tour and a chance to get acquainted with the space and the staff. If you or one of your other children has an appointment, you can bring the younger child along to help get them familiar with the clinic.

In preparation for the first visit, try not to over-prepare your child or say things like "it won't be too bad" as these behaviours often just trigger fear and nervousness rather than providing comfort. When you get to the appointment, be sure to discuss an oral health plan for your child with either the dentist or dental hygienist.

Most importantly, do not wait for an emergency to bring your child to the dentist. The additional stress of pain or injury will make an unfamiliar experience even more difficult for your child.

CHILD ORAL HEALTH CONCERNS

Though baby teeth will be replaced by permanent teeth as your child grows, proper maintenance of their baby teeth can not only prevent child oral health concerns and ensure healthy gums and jaws but also helps to develop good oral hygiene habits that will follow your child through life.

BABY BOTTLE TOOTH DECAY

Allowing your baby to fall asleep while nursing or sucking on a bottle allows sugary liquids to pool around the teeth and may lead to extensive tooth decay. To ensure that tooth decay does not progress unnoticed you should check your child's teeth regularly for any brown spots along the gum line. Frowns or tears when eating cold, sweet, or hard foods may also be signs that your child is experiencing tooth decay.

SNACK CHOICES

Just as with adults, sugary snacking habits in children can greatly increase the likelihood of cavities and tooth decay. Foods which contain high levels of sugar or which are soft or chewy and stick to the teeth are the most harmful as they cause the natural bacteria in your child's mouth to produce high levels of acid which may erode teeth. It is also important to remember that, though more nutritionally sound, natural sugars such as those in fruit can still cause dental decay if the teeth are not brushed regularly and thoroughly.

Along with healthy eating choices, you should try to reduce your child's consumption of sugary foods that are held in the mouth for a long time such as lollipops, hard candies, etc. If your child is going to eat something sugary, it is best to pair it with a meal so that the additional saliva production helps to wash the sugar off the teeth. Generally however it is best to avoid sugary foods to prevent the formation of a sweet-tooth and choose instead healthier options such as:

• Popcorn
• Vegetables
• Fruits
• Nuts & Seeds
• Meat
• Cheese
• Coleslaw
• Pizza
• Plain yogurt
• Eggs
• Enriched or Whole-wheat bread
• Whole grain cereal
• Plain milk
• Tossed salads
• Plain muffins

Though snacks such as raisins, dried fruits, and granola bars are healthy, they tend to stick to the teeth and so are not an ideal choice for snacks.

ORAL HYGIENE HABITS FOR CHILDREN

Even before your child's first tooth appears, you can and should begin an oral hygiene routine. Use a cloth to wipe down your baby's face and gums after every feeding. Once the first tooth appears, use a soft bristled brush to clean the tooth after every meal but do not use toothpaste as children tend to swallow most of it which can be harmful. If you are having difficulty brushing your child's teeth, you may want to try having your child lie down with their head in your lap, or have them stand in front of you with their back leaning against your body while holding a mirror so that both you and your child can see what you are doing.

Children require smaller brushes than adults and flossing should begin only when the teeth begin to touch each other. You child will likely not have the manual dexterity to brush and floss their own teeth until the age of 8 or 10. Establishing a good routine from the very beginning will help your child to get into a habit of oral hygiene.

Once your child begins brushing their own teeth, you may want to use a timer to ensure they are brushing for long enough as well as providing rewards such as stickers for regular brushing and flossing. The best way to get your child to adopt good oral hygiene habits is to model them yourself. If you and your child brush your teeth together ever morning and evening the practice is more likely to be kept up than if you expect your child to form the habit all on their own.
