Why do some people have crooked teeth and how do you fix them?


Everyone wants to have a perfect smile that you see on models and people on television. But if you take a close look at people around you, you will see that people have crooked teeth more than the perfect straight.

What exactly are crooked teeth and its types?

Crooked teeth are those which are simply not the perfect straight ones. The pediatric dentist or orthodontist classify it mainly into broad categories of crooked teeth. They are crossbites and Class II malocclusion. Cross-bites are mainly seen very common among the kids. Cross-bites can also be classified into two categories.

  • Anterior cross-bite: This is most common due to thumb sucking where it results in the upper and the lower teeth are not meeting each other thereby leaving a gap. But the back teeth meet when bitten together. 

  • Posterior cross-bite: This is most common in mouth breathers and teeth are gapped with each other. 

And the Class II malocclusion is when the lower teeth are set far behind the upper ones. It is seen commonly in the mouth breathers. 

And the Class II malocclusion is when the lower teeth are set far behind the upper ones. It is seen commonly in the mouth breathers. 

Reasons for crooked teeth: 

  • Genetical development: Genetics is one of the most common reasons for crooked teeth. It is mostly related to the size of our mouth. Smaller the mouth, greater is the chance of crooked teeth. The jaw development, the skull and the vertebral bone involves the cranial disbalance. And hence raises as a factor for crooked teeth. However, misaligned jaws are the center of the facial growth and also leads to issues of the crookedness of teeth.

  • Imperfect habits: It is very commonly seen when breathed through mouth. The nasal breathing is mostly attached to the proper jaw and teeth development. The expansion of the maxilla and the upper jaw is by the normal breathing through the nose. But if we tend to breathe through the mouth and if it becomes a habit then the obstruction is created to increase the pressure in the airway of the nasal. At this point, it becomes utmost important to consult the doctor to have the breathing pattern corrected.

  • Incorrect lip and tongue posture: Poor lip and tongue posture is also a common reason for crooked teeth. Ideally, the lips should rest on each other but when it does not, its high time we must consult the doctor. 

  • Oral behavior: Thumb sucking and usage of pacifiers should mostly be restricted to avoid the crooked teeth.

    How to treat crooked teeth? 
    An orthodontist like Dr. Nizam would check the pattern of the teeth then she would recommend a solution with either braces or Invisalign. The treatment can be started at any age although there is a specific timing for the treatment duration. However, whenever you feel the first signs of crooked teeth, you should not make a delay in getting checked by a professional orthodontist. 


Is Flossing really required?


We get asked this question on a daily basis. Do I need to floss? Does floss really prevent decay? Does flossing really prevent gum disease? My parents’ don’t floss and their teeth and gums are fine.

One thing is for certain, all dental professionals will tell you that flossing is needed to maintain optimal gum health for all ages.

Brushing alone without flossing does not take care of all the areas on the mouth properly.

A toothbrush is used to remove the plaque from the surfaces of the teeth that you can see. So that means the biting surface, the tongue and palate surface, and the cheek and lip surface of the teeth. After brushing there is still 40% of tooth surface that is untouched and uncleaned. However when you are in braces, the brackets and the wires are in the way and prevent you from getting to even more tooth surface. This is why we then recommend the use of piksters to access the tooth surface under the wire and the sides of the brackets.

Surely My Teeth Must be Clean Now

If you think your teeth are clean after brushing and using a pikster, do me a favour and chew on a disclosing tablet. This will highlight the plaque that is stuck in between the teeth and at the gumline, which will look like a Y shape between the teeth. This is because it is nearly impossible to get a gigantic toothbrush and pikster brush in that tiny little space between the teeth. And guess what? That’s why we then recommend the use of floss.

But Why Floss?


Floss is the only thing small enough to squeeze in between the teeth and go underneath the gum to remove the rest of the plaque that is present.

Some people say ‘but now you’re pushing plaque under the gum’. Well it is already there and by rubbing the floss up and down each side of each tooth, you’re loosening the plaque off the sides of the teeth so that it has the chance to be removed. If you don’t floss at all, there’s still going to be plaque stuck in between the teeth regardless.

Are some people just lucky and don’t need to floss? Well, yes. We do see people who hardly ever floss and don’t have decay between the teeth, and luckily for them they don’t have gum problems. But are you willing to risk it and hope that you are one of those people because they are few and far between.

At first flossing is a bit tricky, like all tasks the more you do it the better you become. Flossing properly should only take 2-3 minutes once you get the hang of it.

How long does it take to straighten teeth with Invisalign?


Invisalign is growing in popularity as an orthodontic treatment because people like that the aligners are clear and nearly invisible, and they can take them out to eat.

One of first questions people ask our Orthodontists about Invisalign is:

“How long will it take to straighten my teeth with Invisalign?”

The simple answer is: “It depends.” For simple cases, treatment time with Invisalign aligners can be as short as six months. Typically, Invisalign will take 12 months to 18 months to straighten your teeth.

For more complex cases such as crowded teeth, the treatment time could be 20 months or slightly longer.

No two people have the same treatment requirements because everyone’s teeth are slightly different which impacts treatment time.
