• What is root canal treatment?

When the dental caries approaches the pulp or the surrounding tissues around pulp and periapical region it is treated with root canal procedure.

Initially these procedures were done in 3-4 sittings which often became tedious to the patient. But now these procedures can be completed in a single day and that too within 45-50 minutes.

The procedure is as follows:

In our clinic we have the best equipments for a successful endodontic treatment some are the apex locator, endo activator, system B obturation system, 12 types of endo files , rotary endo, touch ‘n’ heat system which further help in accomplishing root canal treatment in less time.

Now for a successful endodontic treatment complete removal of the necrotic Pulpal tissue and microorganisms should be achieved.  For this the accurate length of the root canals are determined which is achieved with apex locators and is used routinely in our clinic.



Single sitting root canal treatments are not limited to a group of teeth but can be performed in teeth with swelling and pus discharge also and that too without any pain.

Endoactivators helps in complete irrigation of the root canals by vigorously energizing the Intracanal irrigants during endodontic treatment. It also disrupts the smear layer and biofilm formed which is not achieved by any other equipment.



With the help of rotary endodontics proper cleaning and shaping of the root canals is done within no time. And proper obturation is possible with the help of system B obturation system.

At our clinic we provide the best treatment to the patient with our latest equipment in the least time and that too painless treatment. We have the best dental clinic in Ashok Vihar.

Gum disease is inflammation of tissues surrounding the teeth. It can range from simple inflammation to severe damage to the bone that supports the teeth.

It has 2 forms:

  • Gingivitis
  • Periodontitis

Gingivitis is mild form of gum disease in which there is only swelling and redness in gum. But if gingivitis is not treated in time it can lead to severe bone loss and pocket formation and convert into a disease called periodontitis.


A bio-film is formed on teeth which is called dental plaque. It can be removed by brushing and flossing. This is a reversible condition.  However, if it accumulates on the tooth surface for long period of time a harder deposit is formed which is called tartar or calculus. It cannot be removed by simple brushing. The bacteria in the bio-film release waste products that cause inflammation in the gum leading to severe bone loss, mobility and loss of teeth subsequently. It should be treated as soon as possible and if left untreated the bacteria in mouth can enter blood stream and spread to other parts of body causing heart and kidney diseases.


  • Poor oral hygiene
  • Hormonal changes in pregnancy and menopause.
  • Some diseases like Cancer and HIV interfere with the immune system leads to gum disease.
  • Certain medications
  • Smoking
  • Genetic



  • Swelling of gum
  • Bleeding on brushing
  • Bad breadth or halitosis and bad taste in mouth.
  • Mobility of teeth
  • Receding gums



If you are facing any of these problems you need to contact dentist. It needs to be treated as soon as possible. With time condition worsens leading to severe complications both on general and dental health.

Treatment depends upon the stage of the disease, and categorized as:

  • Non-Surgical

  • Scaling
  • Root planning
  • Curettage
  • Surgical :
  • Flap surgery/pocket reduction surgery
  • Bone grafts
  • Soft tissue grafts
  • Bone surgery
  • Guided tissue regeneration

Recommendation of certain antibiotic is also done to eliminate bacterial infection.


Laser treatment is one of the newest modality of treatment of gum disease.


There is no any serious precaution to be carried out after treatment.All you need is to maintain good oral hygiene.

  • Proper brushing of teeth twice daily
  • Use of fluorinated toothpaste
  • Use of mouthwashes
  • Warm saline rinses

You must  visit dentist for cleaning of teeth  twice a year in order  to avoid all form of gum disease and other related serious complications on health.

Dental Implant: Causes of Failure

Dental implants are designed to be a permanent replacement for a missing tooth or teeth and are also growing to be popular alternative to removable dentures or fixed bridges.

Still some patients do experience some complications. The following are a few of the possible causes and reasons behind dental implant failure:

Success Rates

The majority of the problems that occur after the implant placement are generally minor and easily resolved. If something goes wrong, consult your dentist or surgeon.


Osseo-integration is the formation of functional and structural bond between bone and an artificial implant. This process takes place over several months after the implant is placed in the bone.

The failure of the jawbone to fuse together properly with the implant is considered to be a failed osseo-integration. An implant is failed if it is mobile, falls out of bone or shows signs of bone loss of more than 1 mm even after the first year.

For patients who don’t have adequate bone height, width or length, procedures such as a sinus lift or bone graft can help in increasing space and bone mass loss.

Peri-Implantitis (Infection)

Peri-implantitis, or infection, is a condition that involves inflammation of the gum and/or bone around the implant. A form of periodontal disease, peri-implantitis can cause bone loss and implant failure.


Nerve & Tissue Damage

When an implant is placed too close to a nerve, patients may experience chronic pain, tingling or numbness in their cheek, gums, tongue, lips or chin.

Some bleeding and pain is to be considered normal for a couple days after the surgery, but if the pain is extreme, the bleeding excessive or they it last longer than a few days, one should contact their dentist as soon as possible


Immediate loading is a all-in-one stage treatment method where the crown and abutment are placed on the dental implant right after the implant placement.

The normal process consists of a two stages and provides time for the implant to integrate with the bone before adding the external components.

Overloading refer to failures caused by excessive pressure or forces placed on the protruding abutment and/or crown. These forces easily disrupt the osseo-integration process.

Sinus Problems

An oral surgeon may perform a sinus augmentation procedure, to develop a strong bone foundation. The goal is to create more bone in that area in order to support a dental implant.

Sometimes if the implant protrudes into the sinus cavity, that area can become infected and/or inflamed. Patients should always inform their oral surgeon about sinus related issues prior to the implant procedure.

Other Risks & Causes Of Failure

The following are other risks and causes are:

  • Foreign body rejection–it is possible that a patient’s body will reject the dental implant.
  • Failure of the implant itself–An implant can crack or fracture if it is subjected to excessive external force impact like a blow to the face or excessive pressure over a period of time like grinding teeth or an unbalanced crown.
  • Allergic reaction–While it is quite rare, some patients can have an allergic or inflammatory reaction to titanium.


  • Bruxism (tooth grinding or clenching)
  • Failure to locate a primary nerve in the lower jaw
  • Uncontrolled Type II diabetes
  • Insufficient bone height, width or length
  • Oral or intravenous bisphosphonates
  • Smoking

Veneers Or Crowns


Porcelain Laminate Veneers and Crowns are the successful and popular of all the options available for improving the look of your smile.

What Is Porcelain Laminate Veneer?

  • Porcelain-made translucent, thin laminates bonded to the front surface of a tooth are known as Porcelain laminate veneers.
  • These veneers enhance your smile with little or no discomfort to you.
  • These veneers are indistinguishable from natural teeth and are made individually according the patient’s needs.
  • Porcelain veneers are made to improve the shape, spacing, color of natural teeth.

What Are The Indications For Veneers?

  • Teeth with multiple fillings
  • Odd shaped, cracked, chipped teeth
  • Spaces between teeth
  • Discolored teeth/ crooked teeth
  • Fractured teeth
  • Unsatisfactory shape, size and form of teeth

 What Are The Advantages Of Veneers?


  • minimal tooth preparation
  • short span for results
  • durable

  • highly resistant to external staining


What Happens When I Go For A Veneer?

  • Your dentist will analyze your smile
  • Depending on tooth shaping, anesthesia will be required.
  • Minimal shaping of your teeth is done and an impression is then taken.

 Ceramic veneers take between 1-2 weeks to be made, during which your teeth may be fitted with temporary veneers to prevent sensitivity.

What Are The Post Treatment Care Instructions?

You should:

  • Brush and Floss regularly

How Is A Crown Different From A Veneer?

A crown is known for covering the entire tooth unlike a veneer which covers the front surface of a tooth only.

It often leads to strengthening, weakening or broken tooth.

Crowns are extremely durable, aesthetic and are mostly used for the front and the back teeth in the mouth.


Indications for a Crown

  • Grossly/badly decayed teeth with large fillings / root canal treated teeth

Teeth grinding is also known as bruxism. Let’s discuss about the grinding abnormally and their ill effects on teeth:

  1. What is bruxism actually?

 Bruxism is forcible grinding and clenching of the teeth, usually happens at night, during sleep. Those who suffer from bruxism may have a habit of biting their fingernails or pencils, or chew the insides of their cheeks.

  1. How common is it?

About half of adults grind their teeth at night, and about 20% people grind their teeth in a destructive way. Children also grind their teeth mainly in response to discomfort caused by colds, ear infections or allergies.

  1. What are the causes of bruxism?

 Bruxism probably is caused by emotional factors also such as daytime stress, anxiety, anger, pain and frustration. Certain sleep disorders can trigger grinding of the teeth as well. Those people who are competitive, aggressive may also be at greater risk for bruxism. Alcohol and some types of medications also contribute in making tooth grinding more worse.

  1. Why bruxism can be a serious problem?

 The enamel may become worn during normal chewing actions so the inside of the tooth is exposed. Over time, the worn out teeth may become sensitive due to exposed dentin, and your jaws may even move out of proper balance. If bruxism isn’t treated early enough, it can lead to gum damage, loss of teeth and restorations, jaw-related disorders, soreness and fatigue in your jaw and facial muscles, and earaches or headaches.

Crowns are very important and common form of restoration which maintains our teeth appearance and functions.

People still have some questions in their mind when it comes to get a crown. We here are trying to answer most frequently asked questions about crowns.

  • What Is A Crown Actually? How It Makes A Tooth Strong?

A crown is actually an artificial replacement which restores the missing tooth by surrounding the left out/ remaining tooth structure or sometimes as a covering for dental implant.

The crown maintains the aesthetics and functions like a natural tooth. The crowns are cemented permanently on the remaining tooth or implant and only be removed by a dentist.

  • When A Tooth Needs Crowns?

 After root canal treatment. The crowns are highly recommended following a root canal treatment as after the treatment the tooth loses the resiliency to absorb the chewing forces and becomes brittle. The crown will help to regain the structure of the tooth as well as the function protecting the damaged tooth from fracture or splitting the roots.

  1. For closing spaces between the teeth like chipped, worn out, discolored or poorly shaped teeth crowns can be used.
  1. When the tooth decay involves all the surfaces of the tooth and it is not possible to restore the tooth just by filling, crowns are given.
  1. If a tooth is cracked, dental crowns are a treatment of choice.
  1. Few dental conditions where the thickness of enamel is very less or less mineralized, dental crowns can provide protection to the tooth maintaining the esthetics and function of the tooth.
  1. If a tooth has a large filling and is prone to fracture, dental crowns are given to protect the remaining tooth structure.
  1. Crowns are also used as to make a bridge where the two crowns provide support to a third crown in between them, in case of a missing tooth.
  1. An Implant also needs crowns. Implants inserted in the jaw which acts as a root and the crown is given to replicate the natural tooth. It maintains the esthetics and function in the jaw in case of missing teeth.
  • Crowns Are Made Of Which Material?

There are mainly three types of crowns used in dentistry.

  1. ALL METAL – This is the most basic crown which is used in dentistry but now its demand is reduced due to awareness of the tooth colored crowns. It looks black due to metal and gives an unpleasant look to the patient.
  1. PORCELAIN FUSED TO METAL – This is the most common used crowns nowadays. The crown is made of both metal and porcelain. The metal is on inside and porcelain is on the outside. They are generally used for the back teeth as it doesn’t fulfill criteria of esthetics for front teeth.
  1. ALL PORCELAIN – These crowns are made only of porcelain, due to the revolution in dental industry. They are also known as metal free crowns and have excellent biocompatibility with high strength and fantastic esthetics which ensures long term success.
  • How Many Visits Are Required To Get A Crown Fixed?

The time depends on the tooth which needs the crown. If the tooth is decayed or at risk of fracture or caries reaching to the pulp, then the condition should be treated first before opting for crown.

Otherwise crowns generally requires two steps

  1. Crown preparation where the tooth is prepared and impression is taken of the tooth and is sent to the lab where it will be made. For meanwhile a temporary crown is given.
  1. Second session is when the actual crown is cemented and adjusted.
  • Is The Crown Preparation Is A Painful Procedure? How One Should Prepare Himself For The Treatment?

The procedure of crown preparation is painless. After placing the porcelain crowns, few people experience sensitivity to hot and cold. Therefore it is advisable to consult your dentist to get all information about your teeth structure.

  • Does The Crown Blends With The Natural Teeth Or Stand Out?

Crowns are made after taking the shade from the shade guide to give the crown a very natural look to blend with the natural teeth of an individual. They are given to replicate the natural tooth with its functions intact, therefore not just crown look like your natural teeth, it functions like your natural teeth as well.

  • How Are The Crown Fixed To The Teeth?

Crowns are fixed with dental cement and technique of the cementation is very specific for each type of crown on what quality the crown is made of.

  • How We Should Take Care Of The Crown? How Long Does It Last?
  • There is no time limit for a crown to last. They can last a lifetime and sometime they choose to fall out or become loose.
  • The oral hygiene is very important for a long life of the crown. By keeping the gums healthy and visiting the dentist regularly for cleaning and checkups will keep the gum infections at a distance.
  • Patient with bad habits such as grinding the teeth or forcefully clenching will need to their habits in control by using the other dental appliances to save the crown as well as their natural teeth from excessive pressure.
