Hyperdontia is a peculiar and quite rare dental problem which involves the growth of excess number of teeth. It can appear during birth and last till the primary teeth fall out to be replaced by the permanent set of teeth, or appear with the rise of the permanent teeth. If a person shows a tendency to grow more than 20 temporary teeth or more than 32 permanent teeth, he or she suffers from hyperdontia. 

Where do the additional teeth occur?
The additional teeth or supernumerary teeth can appear anywhere inside the mouth or dental arch, but the most common ones are called wisdom teeth and they grow as anterior molars after a certain age. Extra teeth in new born infants are called natal teeth. Occurrence of more than 4-6 supernumerary teeth is rare, although there have been known cases of more than 30 supernumerary teeth. 

Why does hyperdontia occur?
1. Hyperdontia often occurs in association with a few select disorders like cleidocranial dysplasia, Ehler - Danlos syndrome, Gardner syndrome, and cleft lip and palate. 
2. Although the exact cause of hyperdontia has not yet been discovered, some studies have shown that it might be a result of over activity of dental lamina during the phase of tooth development in infancy. 
3. It could also possibly be due to genetic or environmental factors. 

What problems does it pose and how can hyperdontia be corrected?
1. The existence of extra teeth often causes problems in speaking.
2. It may also cause deformation in the mouth region, and impediments in a lot of other functional activities like eating. 
3. In rare cases, the extra tooth/teeth may be agents of tumors or cysts. 
4. Therefore, treatment must be swiftly undertaken so as to remove the extra teeth and prevent rise of further teeth in the same spot. 
5. Sometimes, hyperdontia also leads to overcrowding and misshapen rows of teeth; this can also be corrected with extensive procedures.

All About Hyperdontia

The last molar teeth in the mouth are called as wisdom teeth. While in some people they erupt completely into the mouth and function with no problem whatsoever, in others, they remain embedded in the bone, erupt incompletely, erupt at an angle, or are covered by bone or a flap of tissue. They are absent in many.
Of late, dentists recommend removal of wisdom teeth, more a preventative than remedial measure. Some of the reasons for wisdom tooth removal are listed below-
Impaction: Often, wisdom teeth do not have enough space to erupt in their normal position. This can only be evaluated properly on an x-ray. If the x-ray shows that the tooth is unlikely to erupt because of being blocked by a root or bone, this needs to be removed.
Pericoronitis: The tooth partially erupts into the mouth but is covered by a flap of gum. This attracts food and bacteria to accumulate, leading to decay and infection, a condition called as pericoronitis. Very common in the lower wisdom teeth, it leads to severe tooth pain, painful swallowing and swelling of the lymph nodes. This is the most common cause for wisdom teeth to be removed. An x-ray will reveal the tooth to be infected and sometimes periapical abscess may also be present.
Cysts: Impacted teeth can develop fluid-filled cysts which can cause severe and even permanent damage to the jaw bone, adjacent teeth and nerves. Dentigerous cysts are the most common type.
Alignment: Misaligned wisdom teeth exert a constant mild pressure on the adjacent teeth which can hamper the alignment and reverse the effects produced by braces. The bite may be altered also, thereby necessitating removal.
Adjacent Tooth Damage: If the malposed wisdom tooth is causing pocket formation or decay in the adjacent teeth, it is time to get them removed.
Recurrent Sinus Infections: With their proximity to sinuses, there could be constant pain and pressure and infection of the sinuses. This is another indication for their removal.
However, not all wisdom teeth need to be removed. If they have erupted fully, are healthy, produce a good bite, and can be cleaned easily, they do not require removal.
During the teenage years and through 20s, check with your dentist on the health of the wisdom teeth. X-rays can be taken to monitor them and for early identification of problems. If they need to be removed, it is easier to take them out when you're young. The bone surrounding the impacted tooth is less dense, and therefore easier. The ability of the body in general and the jaw bones in particular to heal is also better at a younger age. 


Wisdom Teeth - When To Get Them Removed

Toothache is a painful dental condition that affects many people worldwide. At times the excruciating pain can drive a normal person insane. Cavity and tooth decay contribute to toothache in a big way. However, toothache can also be an indication of some serious dental ailments that needs immediate attention. The following factors/reasons can equally contribute to toothache (mild or severe).

Tooth decay: Tooth decay and cavities are synonymous to unhealthy teeth and toothache. Cavities can also give rise to awkward complications like bad breath. Thus, proper dental care and hygiene is of topmost priority. It is highly recommended to brush the teeth three times daily.
Accidental falls: Accidents incurred during sports or games often go unnoticed and untreated. This can invite unwanted complications like broken teeth, infections or inflammations resulting in toothache.
Unhealthy gums: Bleeding, painful and swollen gums and many other gum ailments can severely affect the teeth. At an advanced stage, this can lead to unbearable toothache.
Bruxism: Many people knowingly or unknowingly indulge in Bruxism or tooth grinding. Bruxism can have serious dental implications. It exerts tremendous pressure on the teeth and the supporting tissues. Eventually the jaw muscles also get affected, with toothache being the inevitable consequence.
Decaying enamel: Healthy enamel implies healthy teeth. Factors like excessive intake of sweets, drinks and chocolates play a significant role in enamel decay.  This can have a detrimental effect on the teeth resulting in toothache.
Abscess, a serious dental ailment:  Abscess is the manifestation of dental infections, whereby pus formation takes place between the gum and a tooth. Pus formation can also take place at the base of a tooth resulting in toothache.
Cracked tooth syndrome: A fractured tooth often acts as a catalyst, leading to toothache. The crack on the tooth is so small that even an x-ray fails to reveal it. Factors like bruxism, tooth decay, to name a few; contribute to the Cracked Tooth Syndrome.
The wisdom mystery: Lucky are those whose wisdom teeth erupt completely, at a single go. Impacted wisdom teeth can give a person sleepless nights. Misaligned teeth are no better.
Toothache and periodontal complications: It is a serious condition leading to shooting pain and inflammation. The inflammation and pain affects the root of the tooth immensely. It usually results from infections in plaque formations.
Sinus infections: In many cases, it has been found that sinus infection can lead to toothache. Positioned close to the upper back teeth, the sinuses give rise to what is known as a dull ache.
Toothache can be an amalgamation of many factors. Thus, it is very important to go for periodical dental & full body check ups.

10 Reasons for Toothache

If chewing food and retaining a sparkling smile is not enough for you, avoiding toothaches and a visit to the dentist could be reason enough to maintain healthy teeth. Ignoring your tooth health can lead to many problems. Answer yourself the following question. Would you like your teeth inside your mouth or in a glass tumbler beside your bed at nighttime? 

If you opted for the former, then going through the following tips and advices will go a long way in helping you sustain healthy teeth. They are:

1)  Brush and floss twice a day
Brushing and flossing twice a day, on a regular basis will help you maintain healthy teeth and gums in the long run. The ideal time to brush your teeth is 20 minutes after a meal. Opting for a toothbrush with a small head and soft bristles gives you better access to even the deeper portions of your mouth, thus providing comprehensive cleansing to your teeth. Moreover, softer bristles are generous on your gums as well.

2) Nutrition
Whatever you eat, either protects you or makes you more susceptible to diseases and disorders. This stands true for your oral health as well. As such, choosing the right foods early in your life is of vital importance. Foods such as cold drinks, cakes, candies and other such sugary substances facilitate the growth of germ and bacteria in your mouth, resulting in plaque and cavities. Choosing foods that are low in starch and sugar will reduce the development of germs and help eradicate cavities or plaque in the long run.

3) Smoking
Even the pack of smoke that you buy endorses smoking is injurious to your general health. Smoking causes reduced flow of blood to the mouth, which resultantly leads to increased chances of periodontal disease and mouth cancer. Smoking, moreover causes a decline in the ability of the bones and tissues to revascularize (self-heal). All else apart, just stop smoking.

4) Chewing gums
Chewing gums are highly beneficial especially after a meal. They not only increase the flow of saliva in your mouth, but also improves the flow of blood to your brain, thus enhancing your alertness by close to 10%. In addition, chewing gums help neutralize the acid in your mouth, thus helping you cleanse your mouth.

Tips to Maintain Healthy Teeth

A quite serious bacterial infection, diphtheria is caused by the Corynebacterium diphtheria. It usually tends to affect the throat and the mouth of an affected person, although there are other varieties which can infect your skin as well. However, the most common cases of diphtheria affect the throat and the mouth. 

Symptoms of diphtheria in general
It may take up to five days for symptoms to show up when you are infected with the disease. Some of the symptoms would be:

You neck would swell up due to swelling in the lymph nodes, especially in the neck
Your throat and tonsils will develop a thick grayish membrane 
Your throat may become sore and hoarse
You may face difficulty in breathing, depending on the size of the membrane and the resultant inflammation
You may have difficulty swallowing as well
These are the primary symptoms which will affect your throat in general. Some of the other symptoms that may show up are:

Fever
Nasal discharge
Malaise or a general feeling of discomfort 
Chills
The parts of your body, which are affected the most tend to be your throat, tongue and the neck. The pain tends to persist for quite some time as you recover.

Causes of diphtheria 
Diphtheria is usually spread by the following methods

Airborne droplets: This is possibly the most common method of contracting the disease. This usually happens when a person is infected with diphtheria coughs or sneezes around you. The airborne droplets then travel from one person to another, transmitting the infection. This is particularly the case in crowded area such as public transport and public spaces.
Touching personal items which may be infected: Touching used towels, paper tissues or drinking from an unwashed glass may cause an infection as well. These tend to happen mostly in an indoor setting such as offices and houses. Even toys, door and equipment handles can cause transmission of this virus. 
If you are showing any of these symptoms, it is prudent to go visit your doctor immediately as diphtheria, if left untreated, may also result in serious complications.

Diphtheria - How it Affects Your Throat and Tongue?

Unlike other teeth which erupt at specific period of time, the wisdom teeth, in normal adults, erupt anytime from late teenage years to adulthood. The refined food habits in the recent times have reduced the need for a third molar. Also, our jaw sizes have reduced with evolution, and oftentimes, there is less space for these to erupt completely, causing their impaction. The chances of infection developing within the tooth and in the surrounding tissues is very high, requiring removal. Before you go ahead with removal, know the following four things.

Get a buddy: In addition to the effects of anesthesia, there also would be moderate pain and discomfort, depending on how traumatic the extraction was. It is always best to have someone accompany you for the visit. This also helps you reach home safely without having to drive.
Numb tongue and lips: The wisdom tooth removal is done under a local anesthesia where the entire quadrant is numbed before the procedure. Therefore, the chances of chewing on the tongue and the lip are quite high. Be careful to consciously avoid this as there are a lot of people who do not feel pain, but continue to chew on the tongue or lip and end up with injuries.
Pain Management: Once the effect of anesthesia wears off, the pain will slowly set in, and will depend on how traumatic the extraction was. It is always advisable to take a pain killer before the anesthetic effect wears off, usually 30 to 40 minutes after the extraction process is over.
Diet: For the first couple of days, stay on a completely soft diet with nothing spicy, hard, or hot to eat. One of the best things to have after an extraction is an ice cream, which can be continued for a couple of days after the extraction. Yogurt, smoothies, milkshakes, mashed vegetables and well-cooked rice are all good food choices.
Smoking: If you have had an extraction, avoid smoking for at least a week. The negative pressure created during smoking can dislodge the clot that is formed in the tooth socket. This can lead to a complication called dry socket, which can be very painful. Avoid smoking at all costs, especially with wisdom tooth extractions.
Postoperative follow-up: Based on the complexity of the extraction, a postoperative follow-up would be required. Be prompt in following up with your dentist for suture removal, check on socket healing and postoperative irrigation of the surgical site. Resume routine oral hygiene practices as recommended by the doctor.
Wisdom tooth removal requires a little extra caution as compared to a normal extraction, the ideal thing to do is to follow your dentist s advice.
