My Tooth Gets Dark

My Tooth Gets Dark

Tooth Changing color


My Tooth Gets Dark. How Can I Get My Smile Back?

It is common for teeth to change color before or after a root canal treatment. Usually, after the trauma pigment deposited from the nerve within the tooth can cause the tooth to turn gray or brown. The process of calcification inside the tooth can cause it to turn yellow. The treatment depends on the type and the intensity of the color change.

Internal Dental Bleaching



The dentist can correct the color by performing dental bleaching on the damaged tooth.
The technique involves your Dentist or Specialist Endodontist placing a small amount of extremely strong dental bleaching solution inside the tooth where the nerve was. The dentist will place it through the small hole in your tooth which was used for the root canal. Then, the dentist will cover the hole with a temporary composite filling to seal in the dental bleaching solution for 3-4 days.
You will see that the tooth starts to lighten almost immediately. Your dentist will need to replace the dental bleaching solution 2/3 times to regain normal color of the tooth. Then, a permanent filling will be placed.
A procedure of internal dental bleaching is very stable and it works best for teeth that have changed color brown or gray. But, it is difficult to attain a shade which will match with your other teeth.

Ceramic Veneers and Crowns

The dentist can offer to use a crown or veneer to cover the tooth which changed the color.


A ceramic veneer is a good option for the tooth slightly to moderately dark. Ceramic veneer is a thin ceramic shell which will be bonded to the tooth to change its shape and color. If the tooth is extremely dark the crown will be advised as a treatment option, as the color of the dark tooth can be visible through the thin ceramic veneer. 

Before and After Zirconia Crowns

 Darkness from the root can be visible slightly through the gum tissue. In this case, the internal tooth bleaching with or without a restoration will be a treatment option.

TMJ Syndrome

TMJ Syndrome


 TMJ syndrome

TMJ syndrome


The jaw and your skull are connected by temporomandibular joint (TMJ). When your temporomandibular joint is damaged or injured or you have problems with your face or jaws muscles, it can cause a localized pain disorder called  TMJ syndrome.



Causes of TMJ syndrome include:


-Misalignment (malocclusion) or trauma to the teeth or jaw

-Teeth grinding (bruxism)

-Poor posture

-Stress or anxiety

-Arthritis and other inflammatory musculoskeletal disorders

-Orthodontic braces

-Excessive gum chewing


TMJ signs and symptoms include:

-Pain in the face, jaw or ear area

-Headaches (often mimicking migraines), pain and pressure behind

the eyes

-Pain that feels like a toothache

-Ear pain or sounds of cracking in the ears

-Noise in the ears (tinnitus) or a sense of blocked ears

-Blurred vision

-Tight, stiff, or sore jaw or neck muscles

-Pain at the base of the tongue

-Pain, swelling, or a lump in the temple area

-Difficulty chewing

-Shoulder pain

– Locking of the jaw joint or jaw that goes out of place

-Swelling of the face

TMJ leads to the teeth/jaw injury and incorrect position, teeth grinding, stress, arthritis, and gum chewing.


If you were diagnosed TMJ, Modern Dental Care Mauritius suggests the treatments listed below which work best in combination. You may get feel better if use all of them.

Soft food diet:


  • Cut food into very small pieces so that it is easier to chew.
  • You will be recommended to eat soft food that doesn’t require a lot of chewing, your jaw gets a chance to rest and heal:
  • Yogurt
  • Mashed potatoes
  • Cottage cheese
  • Soup
  • Scrambled eggs
  • Fruit smoothies
  • Cooked vegetables or fruits
  • Fish
  • Grains
  • Beans

Some people feel better after about two or three weeks on this diet. Other people need to be on this diet for a longer time.


Medical treatment for TMJ syndrome can include dental splints, physical therapy, injections of Botox, prescription medications and in severe cases surgery.


Prescription medications:


  • Nonsteroidal anti-inflammatory drugs to relieve muscle pain and swelling.
  • Muscle relaxants help loosen tight jaw muscles.
  • Antianxiety medicines help relieve the stress.
  • Antidepressants can be used in low doses to reduce or control pain.
  • Night Guards

Night Guards are designed to keep your teeth slightly separated and prevent them from clenching, which can provoke an exacerbation of the symptoms of TMJ.




In case of severe condition, you may be advise to use a splint to hold your jaw in place so that the joint can heal. Splints are worn all day round and take pressure off the jaw joints and muscles so they can relax and heal.


Physical therapy


Physical therapy can reduce damage and relieve the discomfort caused by TMJ.

The following 8 exercises will train your jaw muscles to move correctly without causing pain and help you to strengthen them. Do these exercises for 5 minutes twice a day while you are sitting down and relaxed. Make sure that you repeat them on the both sides of your jaws. Keep in mind: every case of TMJ is unique, so these complex might work for some people, but not others.

Composite fillings

Composite fillings


Tooth colored composite fillings


Composite-Fillings-compare -mdc

Composite filling before and after

Nowadays, tooth-colored composite fillings are getting more and more popular. They mimic the natural appearance and do not require much tooth structure remover. Composite fillings can resist the pressure of chewing (small- to mid-size fillings) and have good durability.


They can be used to reinstate decayed or fractured teeth, to change shape/size or color of the tooth, to close gaps between teeth (diastema closure), to restore chipped teeth and to straight or even teeth.


Tooth colored composite fillings advantages

  • They mimic natural tooth look.

  • Tooth-colored composite fillings are attached directly to the tooth so your dentist does not need to remove much tooth structure.
  • composite filling leakage-mdc

    Oral contamination can pass through composite filling

    Composite fillings restore up to 90% of the natural tooth strength.

  • Composite fillings can be repaired. A small area of a composite filling can be removed and replaced without replacing the whole filling

  • They entirely solidify in seconds in comparison with other materials.


Tooth colored composite fillings disadvantages


  • Can be stained with coffee, tea, red wine.
  • Alcohol can damage them.
  • With time bacteria and oral contamination can pass through composite filling and cause tooth decay under the surface of filling. It can lead to serious tooth damage.

Custom made ceramic inlay


The most durable and aesthetic alternatives to tooth-colored composite fillings are custom made ceramic inlays/onlays. They do not change color with a time and cannot be damaged by alcohol and last longer.

Crown After Root Canal

Crown After Root Canal


        Why Should You Have A Crown

            After Root Canal Treatment


crown after root canal


After completing a Root Canal Treatment your tooth may require a permanent dental restoration. The tooth can be fragile and will need to be strengthened. The reasons why it may happen:


Damage during treatment

To reach root canals, a dentist creates an access opening in the tooth through which RCT will be done. This hole (access cavity) may weaken the tooth as in some cases the great amount of internal structure needs to be removed to access root canals. And sometimes the tooth may become vastly gouged out.


Previous Treatment

Pain after composite filling mdc dental clinic mauritius Many teeth that require root canal have already undergone serious treatment such as large fillings or have been fractured and already weakened.

Changes in a tooth dentine

The microbe-killing medicine and other chemical agents which are used during root canal therapy reduce the dentine(hard, calcified tissue beneath the enamel).                                                                                                                                 

Risk after completing Root Canal Treatment

After completing Root Canal Treatment a tooth can be at significant risk of fracture. A dental crown will protect a tooth and will make it stronger. Another issue is an effect of “coronal leakage’’ when bacteria and contamination from the mouth find a way to seep past a tooth dental restoration (filling). It can lead to RCT failure and as result tooth loss.


A coronal-leakage-mdc-dental-clinicCrown After Root Canal Treatment can prevent such dramatic effect.


Studies show that risk of losing a tooth that had a dental crown after root canal is 6 times less than those that had a composite filling.

Survival rates after RCT mdc dental clinic



Placement a crown after root canal for molars (back teeth) become a standard procedure in dentistry as these teeth must be able to cope with heavy chewing pressure (a dental post and core may be needed too).


We advise placing a crown after root canal as soon as possible.

Dr.Vidoushi Puchooa about herself:

As one of the laureates of the 2009 cohort, I had the opportunity to pursue my undergraduate studies at the University of Liverpool (UK) School of Dentistry. Following graduation, I worked in the UK as a general dental practitioner within a team of dentists in a mixed NHS/Private practice providing a range of dental treatment to adults and children.

Types of treatment for adults included scales and polishes, fillings, root canal treatment, extractions, dentures, crowns, bridges, veneers, onlays and inlays, and tooth whitening. Treatment for children included preformed stainless steel crowns, fillings, and extractions.

I also worked in secondary care as a Senior House Officer in Maxillofacial Surgery. I performed surgical extractions of wisdom teeth and ectopic canines, dealt with a range of dental and medical emergencies and performed a range of minor oral and skin surgeries. Academically, I have pioneered a research on reduction of blood transfusion risk in oral cancer patients and carried out multiple audits to keep improving clinical care.

My aim is to provide the best standard of care to all patients in a safe environment and I am continually updating my skills to be able to do so. I believe in the practice of minimally invasive, evidence-based dentistry. Prevention, as well as patient education, are at the core of my daily practice. Working as a team with patients, I am committed to achieving desired results and meeting expectations.
