Before and After: Crossbite of a Front Tooth

In this before and after, you are going to see how to fix a crossbite of a single front tooth. The pictures below are from one of our actual patients with an anterior crossbite.

A crossbite is an orthodontic term for when a top tooth improperly bites behind a bottom tooth. A single tooth crossbite is also known as a scissor bite.

When a child has a crossbite there are usually other orthodontic problems as well. Here is a picture of what a single tooth crossbite actually looks like:

Crossbite of front tooth

Crossbites occur alongside other orthodontic problems. This picture shows a child with (1) crowded teeth have prevented a tooth from coming in, (2) a top tooth is biting behind the bottom tooth instead of properly in front of it, and (3) plaque is accumulating because crooked teeth are hard to keep clean.


A crossbite needs to be corrected because it can:

  • put the tooth at risk for chipping and breaking
  • interfere with proper growth of the jaws
  • cause speech problems
  • loosen the tooth by damaging the bone around the tooth
  • create emotional stress in school-aged children

Fortunately, these problems can be avoided by visiting the orthodontist at the right age.

The best time to treat a single tooth crossbite is when it is first observed. For example, the best age for this child to visit the orthodontist would be age 8 because the tooth that is in crossbite (the maxillary lateral incisor) came into the mouth at age 8.

The best way to treat this child’s crossbite, impacted tooth and crowding is with braces.

Braces start to fix a crossbite of a front tooth

The first day braces are placed is always exciting! You can see that the braces are on all the teeth and that a wire connects the braces together. The blue color on the braces is the piece that holds the wire onto the braces.

After 8 weeks, the tooth is out of crossbite and the smile looks better. In a few more visits, the teeth are straight and the impacted tooth has come into place.

Crossbite fixed with braces

After a few months, braces fixed the front-tooth crossbite. The smile looks great now that the teeth are so straight. This is the same child in the previous two photographs – an actual patient of Dr. Viechnicki.

The treatment of the anterior crossbite was a success! The child loves his new smile and is looking forward to a lifetime of better health.

    Just came across your blog about overbite correction. When I needed braces as a child 55 years ago my Dad was only making $45 a week and couldn’t afford them. The dentist pulled my eyeteeth for $7 instead. I have never smiled with my mouth open. Thankfully today three of my grandchildren have beautiful teeth thanks to being able to have braces. By the way, the braces 55 years ago would have cost my Dad $450-ten weeks pay. How wonderful that all my grandchildren can smile with confidence. I’m not sure they realize how fortunate they are-but I tell them often! Keep up the good work.

  4. There is a critical pbrolem facing many patients with neurological syndromes, or depressive disorders. After taking anti-convulsants OR ANTIDEPRESSANTS for YEARS..our teeth have literally dissolved and our bones have turned to rubber..why? Because these medications, which we MUST take..start messing about with our ability to absorb Vitamin D and Calcium. This was first discovered in 1970. As dental practitioners, certainly you know the rule, BAD TEETH, BAD HEART,BAD HEALTH. I know it because 1) I have epilepsy, and 2) am a forensic anthropologist. Of course, insurers everywhere deny dental insurance to thousand of people like me because they know the truth. So now, we must convince the major health insurance companies, that this is not merely a pbrolem of dissolving enamel it is a systemic pbrolem demineralization of teeth and bone alike. Hey, it’s great to have straight, white teeth but dental health plays a major role in health throughout the body! Calcium makes up 75% of the body and is used EVERYWHERE..not just to build bone, but needed to trigger hormone production, fire up the brain, even plays a role in how you feel.. Why isn’t this a bigger issue? This doesn’t just happen to people with disabilities..it’s also a pbrolem in older people with osteoporosis. You might be looking at your own future..so if you guys can make some noise to draw attention to this pbrolem, there’s a few million of US out here that would sure appreciate it! Thanks!

  5. Wow, those teeth look perfect! I was wondering, how long did the child have those braces?

    The project is located at the axis of Thăng Long Avenue, in the area of Tây Mo – Đại Mo Ward. It covers 280 hectares; however, the construction density is only 14.7 per cent.
    VinCity Sportia spends most of its space to develop public facilities including the largest outdoor sports park in Việt Nam with more than 1,000 gym machines, eight utility parks, 200 outdoor sports fields, eight indoor and outdoor swimming pools, more than 60 children’s playgrounds and 58 relaxing hubs with gardens and walking paths.
    VinCity also owns a comprehensive system of education, health, entertainment and leisure facilities in accordance with Singaporean standards, including an education system from kindergarten to multidisciplinary school including Vinschool, Vinmec International Hospital, Vincom Centres, crowded commercial streets and three BBQ parks.
    VinCity Sportia will also be managed in accordance with VinCity standards from Vinhomes investor to maintain the best environment and facilities. In particular, the security system includes security cameras, a secure elevator using resident cards and a fire safety system with shelters and fire doors.
    In order to make the urban model of “Singapore and beyond” more accessible to the population, Vinhomes and Techcombank have combined to offer a financial solution for customers. Accordingly, customers buying in VinCity Sportia receive maximum financial support. With only 10 per cent of the apartment price, customers can sign a sale contract. The next 20 per cent are paid gradually over six months after signing the sale contract, and for the remaining 70 per cent customers are entitled to a 35-year loan. The payment is only several million VNĐ per month.
    VinCity Sportia is the second project launched in HA NOI in 2018 under the VinCity brand. Modern and convenient, the outstanding point of the VinCity model is the large ecological space, honouring healthy lifestyles and the balance between an active lifestyle and nature. — VNS
