Dental Sealants

Dental sealants are the thin plastic coating applied on the surfaces of teeth usually on back teeth (the molars and premolars) to help prevent tooth decay. Dental sealants acts as a protective shield for each tooth. This article discusses all about dental sealants.

Why are dental sealants placed?
Though brushing and flossing removes leftover food particles and plaque from the teeth, they cannot get in to all the crannies and nooks of back teeth for removing food particles and plaque, these areas become more prone to tooth decay. Dental sealants protect these areas from decay by sealing out and providing smooth surface covering to the teeth.

Who are the candidates for dental sealants?
Since children and teenagers are more likely to develop tooth decay, they are obvious candidates for getting sealants. However, adults can also benefits from sealants.

As soon as molars and premolars come in, children can get dental sealants. This will help protect teeth until the age of 14.
Sometimes dental sealants may also be appropriate for baby teeth, when the child’s teeth have deep grooves and depression. As baby teeth plays an important role in making space and holding permanent teeth, it is essential to keep these teeth healthy.

How are dental sealants applied?
Applying dental sealants is a painless process. The dentist will take only few minutes for applying sealant on each tooth. The procedure is simple and involves the following steps:

  • The teeth to be sealed are cleaned first.
  • Then each tooth is dried, cotton or other absorbent material is put around the teeth for keeping it dry.
  • An acidic solution is placed on the chewing surfaces of the teeth to roughen them that helps the dental sealants to bond with the teeth.
  • Then the teeth are rinsed and dried.
  • Sealants are painted on the tooth, where it directly bond with the tooth and hardens. A special curing light is sometimes used for hardening sealants.

How long do sealants lasts?
Dental sealants can help protect teeth from decay for about 10 years provided; it should be monitored by dentist. They need to be checked for wearing or chipping at regular dental visits. If required, the dentist will replace it with new sealants.

Factors Affecting the Success of Dental Implants

Dental implants are designed in such a way that provides a permanent solution for the people with missing tooth/teeth. As with other surgical procedures, dental implant surgery may also be affected by number of internal and external factors that can cause complications or even failure of dental implant surgery. This article contains some facts that can affect the success of dental implant surgery.

Factors Affecting the Success of Dental Implants:

1) Sinus Problems
This problem can be the major challenge for the Implantologists when placing dental implants in the upper jaw. In addition to the sinus problems present, insufficient bone quantity and quality in the upper jaw can make placing the dental implants difficult. For developing strong base for dental implants, your oral surgeon may perform the sinus augmentation. In this procedure, the existing bone is lifted in the sinus cavity thus creating enough space for bone grafting. The aim of this surgery is to create enough space for dental implants.

If the dental implant protrudes in the sinus cavity, the area can be inflamed and infected. For detecting, the sinus problems, an x-ray and CT scan are taken that follows these surgeries. This is why it is very important to inform the dentist about the problems a patient is suffering from.

2) Per-Implantitis
This infection can stay in when bacteria is present during oral surgery. This condition involves gum inflammation and also infection in bone that surround your implant. This can cause some complications. Peri-implantitis, a form of periodontal disease can cause implant failure. In some cases, it can be treated, but mainly implant has to be removed. Patients with poor oral hygiene, diabetes and people with thin gums are at high risk of developing this infection.

3) Nerve and Tissue Damage
This problem can occur very rare. In some cases, when dental implants are placed, it can cause damage to the tissues and close by, especially when an implant is placed too close to the nerves. The patients might feel tingling, pain, numbness in cheeks, lips, tongue and chin. This damage is temporary or permanent and implant might have to be removed. This issue is often caused by the mistakes made by inexperienced surgeon.

4) Overloading
In some cases, the surgeon decides to perform loading immediately during dental implant surgery. This involves one stage treatment method where abutment and crown are placed on the implant soon after the implant is inserted. Normally, the process comprises of two stages that provides time for the implant inserted in the jaw to fuse with the jawbone. Then other components that protrude above the gums are added later. Since implant fusion with jawbone is incomplete, it can lead to complications and even failure of dental implant.

Overdose of Micronutrients

Micronutrients are essential for the normal helth. However, if you taken them more than advised, that is, in overdoses you may face troubles instead of benefiting. Optimum levels are good to health. Micronutrients when taken in excess are known to have some negative effects on health.

In this article, we will have a discussion on harmful effects of overdose of micronutrients.

Overdose of Vitamins

Vitamin Effects
Vitamin A Dizziness (a feeling that you are about to fall), headache, may lead to coma and death at extreme cases. Double vision, birth defects in infants when take in higher doses during pregnancy, weakens bones.
Vitamin D Instead of depositing calcium on bones, it removes calcium from bones making them soft and easy to break.
Vitamin E Overdose through dietary sources is very rare. Generally found in people taking supplements. Higher doses can cause severe diarrhea, abdominal pain, excrete excess vitamin E through feces, prevents blood clotting in injury leading to excessive blood loss.
Vitamin k It is rarest form of overdoses. But the effects are severe when overdose occurs, it leads to damage of cells and cell linings, liver damage at extremely higher doses of vitamin k
Vitamin B1 Increases sweating, a sense of vomiting, restlessness, water is retained inside the body leading to swelling.
Vitamin B2 Change in urine color (yellowish-orange), diarrhea, frequent urination.
Vitamin B3 Increase pulse rate, flushed skin, itching, a sense of vomiting, pain in the abdomen, sometimes vomiting.
Vitamin B5 Overdose is very rare but at extreme cases leads to diarrhea.
Vitamin B6 A burning sensation in the heart, sleepiness, stomach pain, vomiting sensation, loss of hunger, headache.
Vitamin B7 No symptoms of overdoses seen in normal persons. In case of pregnant women, it may lead to miscarriage.
Vitamin B9 Very rare. In extreme cases, lead to heart attack, liver and prostate cancers.
Vitamin B12 Itching, diarrhea.
Vitamin C Abdominal and muscle pain, diarrhea, stomach upset, indigestion problem, rashes on face, increased stress, weakness results due to break down of red blood cells. In very rare cases, it causes stones in kidneys, decrease intake of iron and copper by the body, tooth decay, severe back pain.

Overdose Of Minerals

Mineral Effects
Calcium Leads to formation of kidney stones, feeling of sleeping, weakens muscles, frequent urination, vomiting sensation, create confusion, constipation(difficult to release feces).
Sodium Major effect is seen in case of heart, it increases blood pressure and ultimately increase chances of heart attack. It is one of the electrolyte to maintain balance, so overdose results in altering functions of kidneys.
Chlorine Impairs acid-base balance in the body, increase blood pressure, difficulty in breathing, convulsions(uncontrolled contraction of muscles), uneven heart beat.
Magnesium No severe effects are seen. At extreme cases, it may alter kidney functioning, sometimes lead to uneven heart beat.
Manganese Have effects on nervous system leading to nerve disorders, irritation, hallucination (similar to imagination)decrease copper and iron levels in the body.
Zinc Headache, vomiting sensation, weakness, decrease hunger, decrease copper levels as well as good cholesterol levels.
Selenium Hair loss, weakness, slightly damage to nerves, nausea(sense of vomiting)
Potassium Alters heart beat, a feeling of burden in the chest, paralysis(some organs become non functional), vomiting
Iron Constipation, vomiting, stomach pain, joint pains, weight loss, infertility, neural problems, sometimes lethal (can lead to death.)
Iodine Goiter (enlargement of thyroid gland), muscle weakness, depression, weight gain.
Fluoride Abdominal pain, abnormal taste, weakness, vomiting sensation, tremors, irregular heart beat.
Copper Damage to brain, nerve disorders, lead to Alzheimer’s(forgetfulness),
Phosphorous Decrease calcium and magnesium levels in bones leading to loss of bone density, increase blood pressure. At extreme cases, lead to death due to bone and heart related diseases. Create imbalance in levels of electrolytes.


Get to Know Dental Implants

Dental Implants are metal devices fixed surgically in the jaw bone to replace the missing teeth. They appear to be same as actual tooth. The feeling of dental implant is different as compared to other teeth replacements while chewing because they lack connective tissues called as periodontal ligament. In this article, we will discuss dental implants from different points of view such their need, people who need these implants, the procedure of implanting, etc.

Need for dental implant
People who lost their teeth or tooth because of some infections, gum disease, injury or an accident that causes embarrassment, gaps between the teeth, difficulty in chewing, speech becomes a problem etc.

Dental implants can overcome the problems associated with missing teeth such as when eating the food. Dental implants improve the speech of wearers, and help them speak better.

Time involved in this procedure
Time involved in having dental implant depends upon the number of teeth to be replaced, and the person’s health. This will also let the dentist and patient know about the number of visits the person has to make throughout the dental implant procedure. Normally the amount of time taken is 6-8 months.

Who require dental Implants?
People with healthy gums and much bone space that can hold the implant are suitable for dental implants. It is important to know about your health before going for dental implants.

People who are young whose jaw bones are still developing should not go for dental implants, and the same applies in case of pregnant women and people who are suffering from any chronic disease. It is sensible to update your condition of your health and let the dentist know about it.

Dental implant procedure comprises the following procedures, namely:
First phase
In the first phase, local anesthesia is given to numb the entire mouth, then an incision in the gums is made where the implant has to be fixed. The jaw bone is drilled to make space. Then, implants are screwed in this space either manually or with the help of implant drill. A second component is screwed into the implant, and will be there during the healing period. One or two stitches are performed to close the gums.

Second phase
In the second phase, an incision is made again for exposing the implant, then an extension is made to the implant to make a new crown sit on it. Then, the dentist takes the impression for a crown. Finally the crown is placed.

Care of dental implants
Your dentist asks you to brush and floss as you do with your natural teeth. Make sure to get the newly implanted tooth regularly checked by dentist to avoid complications.

Dental implants once implanted, you need to take enough care of them. Visit your dentist every six months to avoid oral problems. (more…)

Get to Know about Dental Decay

Dental caries is a common health issue. Dental decay or tooth decay, also called dental caries, happens when the enamel and dentin in teeth are softened by acid attack that leads to cavity (hole in the tooth). Dental caries occurs commonly in children, and young people reaching adulthood. In this article, we will discuss dental caries, signs and symptoms, prevention and treatment.

There are certain causes for tooth decay, when sugar in food reacts with the bacteria present in mouth which forms acid. This acid attacks the teeth and begins to dissolve the outer layers of teeth (enamel). Not only are sugary food harmful, there are other food that react with bacteria and or plaque. Acidic and sugary food and drinks increase the risk of decay.

Signs and symptoms
Tooth decay may not show any signs or symptoms in early stages. But there might be toothache or sometimes is visible as a cavity when dentist examines your teeth. Small cavities are much easier and simple to treat instead of making the problem big and treatment more complicated. However, if the decay is major, it has following symptoms:

  • When taking hot, cold or sweet food some pain and tenderness is felt.
  • Appearance of black spots on your teeth.
  • Severe tooth pain.
  • Foul (bad) breath
  • If there is unpleasant taste in your mouth.

Treatment for dental decay (caries)
If the decay is in early stages, the treatment is simple and easy. The dentist removes the decayed portion with the help of hand piece (dental tool) and filling is done to restore the tooth. If there is an advanced decay, it is treated by root canal treatment. The dentist will remove the infected nerve from the tooth with the help of small dental instruments and filled by a material gutta percha. Then crowning is performed for full restoration of the tooth. If the decay is severe, it infects the other teeth. In such a case, the tooth has to be removed.

Prevention of dental decay
Following are the ways to prevent dental decay.

  • Diet plays an important role in oral health, so take healthy and balanced diet as deficiency of some vitamins and minerals also causes gum problems.
  • As far as possible, avoid acidic foods and drinks, as they may chemically react with the bacteria in the mouth.
  • Drinking water after every meal is a good practice so that there are no left-over food particles in the mouth.
  • Before going to bed, brush and floss. This will keep your teeth clean.
  • Intake of sugary food should be minimized.
  • See dentist once in every six months.

Going for regular checkups is a good practice. Dental caries in early stages can be simply and easily treated. If you ignore dental decay, it leads to more complications later, and may make treatment more difficult.
