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

What you must know before you get root canal treatment

Root canal treatment also known as endodontics is performed to treat and heal an infected or badly damaged tooth rather than removing it. When your teeth start decaying, you do not feel any pain for a very long time. However, gradually the darkening of your tooth color may become prominent which could mean that the tooth nerve is dying or has died. That's the time you will need root canal treatment which involves cleaning of the canals inside the roots of your tooth.

Why you may need the root canal treatment

Teeth consist of a soft core known as dental pulp. This pulp goes beyond the crown &#x2013; the noticeable part of your tooth to the root tip inside your jawbone. The pulp contains blood vessels, nerves, and connective tissue. So when your tooth is damaged or has a severe cavity, bacteria can easily make their way through the pulp. Symptoms and signs of a sore tooth include a hole in your tooth, a swelling around the regions of your face and neck, gum swelling, tooth pain or a toothache and temperature sensitivity. If it is left untreated, the decaying material and bacteria can cause a tooth abscess or severe infection, resulting in a bone loss, pulp death and even loss of the tooth itself. The root canal treatment is the best way to save the damaged teeth and escaping the painful process of extraction.

What does the treatment involve?

The purpose of the treatment is to free your root canal from every possible infection. The root is then cleaned and filled to avoid any further infection.


	
	Root canal treatment is a skilled procedure which is time-consuming and usually requires from 2-3 visits to your dentist.
	
	
	In the initial stage, the infected pulp is isolated to drain out abscesses (if any), followed by the cleaning of your root canal which is then prepared for a temporary filling.
	
	
	Your tooth is then left to settle down.
	
	
	In the next visit, your tooth is checked to see whether it&#x2019;s free from all forms of infection so that it can be permanently filled.

What You Must Know Before You Get ROOT CANAL Treatment

Root canal treatment is a procedure to save or repair a decayed tooth. Without proper treatment, the decayed tooth might get infected and adversely affect the health of the gums as well as rest of the teeth. Abscessed tooth (pus formation in a tooth owing to an infection) may also pose as another major complication if this condition is not treated at the right time. In this procedure, the pulp and the nerve of the decayed tooth are removed; this absence of a nerve in your tooth should not affect your daily routine and also not inflict any pain.

When is root canal treatment needed?
Root canal treatment is only required when dental X-rays show that the pulp has been damaged by a bacterial infection. The pulp will begin to die if it's infected by bacteria, allowing the bacteria to then multiply and spread.

The symptoms of a pulp infection include:

pain when eating or drinking hot or cold food and drink
pain when biting or chewing
a loose tooth
As the infection progresses, these symptoms often disappear as the pulp dies. Your tooth then appears to have healed, but the infection has in fact spread through the root canal system.

Further symptoms eventually occur, such as:

pain when biting or chewing returning
swelling of the gum near the affected tooth
pus oozing from the affected tooth
facial swelling
the tooth becoming a darker colour
It's important to see your dentist if you develop toothache. If your tooth is infected, the pulp can't heal by itself.

Leaving the infected tooth in your mouth may make it worse. There may also be less chance of the root canal treatment working if the infection within your tooth becomes established.

Antibiotics   medication to treat bacterial infections   aren't effective in treating root canal infections.

What happens during a root canal procedure?
A root canal can be performed by an endodontist (root canalling specialist) or a dentist. To treat the infection in the root canal, the bacteria need to be removed. This can be done by either:

removing the bacteria from the root canal system (root canal treatment)
removing the tooth (extraction)
At the very onset, an X-ray will be performed to see the size of the infection and the condition of the surrounding gums. The dentist will then apply anesthesia on that spot. It is important to keep the spot as dry as possible. Next, the dentist will put a rubber sheet around your teeth, after which a hole will be drilled to remove the decayed tissues. After the process, you wash your teeth, either with sodium hypochlorite or normal water.

Before having root canal treatment, you'll usually be given a local anaesthetic. This means the procedure shouldn't be painful and should be no more unpleasant than having a filling.

Root canal treatment is usually successful. In about 9 out of 10 cases, a tooth can survive for up to 10 years after root canal treatment.

Wisdom teeth are known to be the final molars to grow out and they complete the set of permanent teeth. They generally start to erupt during the late teens or in the beginning of twenties. 

In case of some people, there is a possibility that the wisdom teeth may never erupt, while others may even grow four and more wisdom teeth. 

Do all wisdom teeth create dental problems?
No, if a wisdom tooth has completely erupted through the gum and tissue, without actually harming the teeth next to it, it does not require to be extracted. But, this is only if the individual is able to clean and brush it thoroughly. The wisdom teeth should be properly examined and dental care is necessary to prevent any complications. 

When do wisdom teeth need extraction?
Proper oral care of the teeth will keep them healthy and clean. But there may arise a situation, in which the removal of the wisdom teeth is quite necessary:

1. In certain cases, the wisdom tooth may erupt at a weird angle, compromising the teeth next to it. This may make it difficult to clean the teeth thoroughly, thus resulting in the onset of bacterial growth and periodontal disease. In this case, the wisdom teeth should be removed as soon as possible. 

2. While the wisdom teeth grows out, it may happen that there is not enough space for it to grow properly. As a result the adjacent teeth may face pressure due to crowded teeth, leading to headaches, toothaches and jaw pain. It is best that the wisdom teeth is extracted in this situation.

3. In case a wisdom tooth develops a cavity, it should be extracted. 

4. An impacted wisdom tooth, that is, if it has only partially grown out of the tissue, should also be extracted before it can cause serious complications.

All About Wisdom Teeth

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.
