Invisalign® Treatable Cases

Orthodontics & Invisalign

Depending on the complexity and severity of the problem or combination of problems to be treated, Invisalign aligners can be used individually or combined with braces. Invisalign can be used for treating the following dental problems.



An overbite is when your upper teeth are positioned too far forward in front of the bottom teeth when you close your mouth. It can cause difficulty while chewing and biting food. In mild cases of overbite, Invisalign can be used to move teeth to align them in a correct position. 

Invisalign® For Overbite



An underbite is when the bottom teeth are in front of upper teeth and are unable to contact properly when the mouth is closed. This can cause rapid tooth wear as well as impede proper speech. Invisalign can position the lower teeth back so they are more naturally positioned behind the front teeth.  

In moderate cases of underbite, braces may be combined with Invisalign. Severe underbites can’t be treated with Invisalign.

Invisalign® For Underbite



A crossbite is the upper teeth are inclined toward the inner side of lower teeth rather than outside. Invisalign can be used to correct the teeth positioning and treat a crossbite.


Gaps in Teeth

Excessive gap between teeth is not only aesthetically unpleasing but can cause food impaction between teeth and gums, leading to pain and gum disease. Per arch, Invisalign can reliably close up to 6mm of space. For larger gaps, Invisalign has to be combined with braces as a part of the treatment plan.


Open Bite

When upper and lower teeth don’t meet on closing the mouth, (can be due to an occlusal interference). Open bite can be fixed by an Invisalign by aligning upper and lower teeth into their respective correct positions so they can meet and close properly.


Crowded or Crooked Teeth

Due to a lack of sufficient space to accommodate all teeth in the jaw, the teeth end up twisted and overlapping each other. This is known as crowding and can lead to gum disease due to the lack of proper access to maintain oral hygiene. 

Invisalign® For Crowded Teeth


For molars, Invisalign is able to rotate the teeth no more than 20 degrees. The degree of rotation can be more for canines, premolars, and incisors. For mild to moderate cases of crooked and crowded teeth, Invisalign can be a viable treatment option.

To correct alignment, teeth might have to be forward or backward tilted. A tilt below 45 degrees is easy for Invisalign to employ.


After the initial consult with your orthodontist, a treatment plan is devised according to the problems that need to be fixed. If you are a candidate for Invisalign, intraoral digital scans are taken by your dentist which are then sent to fabricate customized clear aligners. These aligners are custom made to apply pressure on specific teeth to move them into place, and are replaced after every two weeks or so.

Are You Looking For A Dentist in Port Coquitlam?
We Are Accepting New Patients!


  • I have been a patient of Dr. Chahal’s for a year now and he is the best dentist I have been to. I have tried out a few over the years. He is friendly, super knowledgeable and genuinely cares. I would recommend this dentist to anyone who is afraid of dentists or anyone who is looking to switch because they are unhappy with their current dentist. He is wonderful. And he is young so he won’t be retiring anytime soon. (I hope!) Five-star dentist. Hands down.

  • I have been seeing Dr. Chahal for two years now. He is a great dentist. He takes the time to explain procedures and options and he always has time for questions. He makes me feel comfortable and confident in the dental procedures we decide on.

  • My Wife, son, and I have been Dr. Chahal’s patients for at least 5 years and I would say that he is the best dentist we have had. He makes you feel comfortable and relaxed when visiting him. I would recommend him to anyone looking for a dentist.

  • Dr. Chahal is the best dentist I’ve ever had, and as someone who has had quite a bit of dental work, that’s saying a lot. He’s a genuine and personable guy who does excellent work, and does not quit until you’re happy with the results.

  • Just returned from Dr Chahal—once again, impressed with the level of comfort and professionalism Dr. Chahal provides his patients—procedure done quickly and painlessly

  • Dr. Chahal and his staff are very informative and genuinely caring. They go above and beyond to ensure each dental appointment is a positive experience. Dr Chahal and his staff explain all procedures throughly and encourage you to ask questions if you have any. Thank you for being so helpful and gentle! I recommend you to all my friends and family.

  • Dr. Chahal and the staff are very professional and informative about the procedure(s) required. What I appreciate the most is the fact that they really care about you and ensure that you are well informed before any procedure is started. He has performed 2 very difficult crown replacements on me in the past 3 months and the results have been very good. Visits to the dentist have never been my favourite activity, but the care, comfort, and friendliness provided by Dr. Chahal and his staff have made my dental appointments a far less stressful experience.

  • I have always been very nervous about visiting the dentist until I started to see Dr. Chahal. He is very personable, extremely knowlagble, and 110% dedicated to his patients. I feel relaxed and very comfortable at all of my appointments. He is wonderful with my 11-year-old son. He says he is the best dentist ever!! I would highly recommended him to anyone:)

  • I just had 2 wisdom teeth removed, Dr. Chahal and his staff did everything to ensure my comfort. Though it was uncomfortable and painful after the fact, this was certainly not his fault! He followed up with a phone call in the evening to see how I was, which I found comforting and was grateful for. All in all, I would highly recommend Dr. Chahal to anyone looking for a dentist.

  • Dr. Chahal is very professional and very thorough, he even offered a few tid bits about the medications he would be using during my procedures. He did a thorough exam while explaining the options for each issue I had. I needed a root canal and he asked me if i knew anything about it. I explained the horror stories I had and he did a fantastic job in making me comfortable and explaining the procedure in a simple yet understandable manner. He also followed up with a phone call in the evening to ask if i had any questions and reiterated some calming suggestions. A few days after the procedure, I felt great and know I was well taken care of by the staff and Dr. Chahal.

  • Dr. Chahal is amazing. I am 30 years old and I had avoided seeing a dentist for years because I was terrified of the needles and what they might find. I first saw Dr.Chahal when I was 25 and, ever since, he has made me feel like family and right at home. He is very personable and makes sure that I understand what it is he is doing and why, and has single-handedly eliminated my fear of going to the dentist. I honestly have almost fallen asleep a few times in his chair, that is how comfortable he has made me and I wouldn’t want to have to ever see anyone else. I highly recommend anyone to see him and I have praised his work to all of my friends.

  • I hand’t seen a dentist in years because I was so afraid!! I was scared of needles and the work I needed. Dr. Chahal and his staff helped me and worked me up to appointments without needing sedation. He is great with needles and genuinely cares about his patients. I’m very happy I found him!

  • I am impressed with Dr. Chahal’s ability, his people skills and his dedication. He is approachable and an excellent listener. If you are upset, he comforts you. Personally, he has replaced old fillings, 2 crowns and has completed some dental cosmetic work. As he works, he asks how you are doing and let’s you know when it is very important to be still. Before he begins he takes the opportunity to educate you on your teeth and explains the procedure he will follow. He has phoned me in the evening to check on my status following a challenging session. When he gives me the freezing shot, I barely observe the needle prior to the shot and do not feel the needle break my skin. If you have any apprehension about dentists, give Dr. Chahal a chance. He has your best interest at heart.

  • can’t say enough about Dr. Chahal and his assistant, Kim. His dental work is excellent! He is the only dentist I have been to who can give a needle with NO pain. Excellent! He has done extensive work (posts and crowns, bridges, etc.) in my mouth and all of it was not only painless, tension free, but was also of the very highest quality. I highly, highly recommend Dr. Chahal to anyone who wants the VERY BEST! The staff are also efficient, helpful, and friendly. A great experience on each visit. Thanks so so much!

  • Great demeanour, very knowledgeable. I appreciate the fact that he treats me like a friend and not a number.
