Closing Teeth Gap, or Removing Diastema for Beautiful Smile

Share This Dental Story |

A Diastema is a space or “gap,” most often between the two upper front teeth. At some stages of dental development, it’s normal to have a Diastema (tooth gap), and the space eventually closes after the eruption of the permanent canine teeth. However, in some people, it does not.

Gaps between teeth can occur naturally or when teeth have been lost. The term Diastema is used to describe open spaces between the upper incisors (front teeth). A Diastema is created by an unequal relationship between the size of the teeth and the jaw. Occasionally, the pulling action of a labial frenulum (tissue around the lip) can push the teeth apart creating a central Diastema.

Patients who have too much room between teeth can help fill in those gaps with expert cosmetic dentistry techniques. Many patients find that porcelain veneers or dental bonding create the illusion of well-spaced teeth.

Takashi Tsuji at the Tokyo University of Science, Japan, and his colleagues took single-tooth mesenchymal and epithelial cells – the two cell types that develop into a tooth – from mouse embryos. They stimulated these cells to multiply before injecting them into a drop of collagen gel. Within days, the cells formed tooth buds – the early stage of normal tooth formation. The team then transplanted these tooth buds into cavities left after they had extracted teeth from adult mice. There, they developed into teeth with a normal structure and composition. The engineered teeth also developed a healthy blood supply, and nerve connections.

Previous approaches to regenerating teeth have involved growing them in the kidneys of mice before transplanting them into the mouths of other mice. “This study represents an important contribution to the field of tooth regeneration” because it demonstrates how teeth can be grown directly in the mouth, says Jeremy Mao, at the Columbia University College of Dental Medicine in New York, US. But Paul Sharpe at Kings College London, UK, notes that earlier studies have shown alternative methods of regenerating teeth directly in animals’ mouths.

He says Tsuji’s approach is different from earlier methods because it involves culturing the cells in a collagen gel. But according to Sharpe, the advantage of using such a gel mixture remains unclear. Since mesenchymal and epithelial cells have the potential to develop into other organs and hair follicles, Tsuji hopes his method could eventually be applied more widely. “We hope to collaborate with dentists and clinicians in various fields to develop artificial organs for people,” he says.

There are four basic choices for diastemas (teeth gap):

• Do nothing and enjoy the characterization of your personality while smiling
• See an orthodontist who can close these spaces down through braces and essentially move all your teeth around over the course of treatment. Treatment may take one to four years depending on the case. This is a very good choice and provides the least intervention to the individual tooth.
• Choice three involves the use of porcelain veneers. These are micro thin pieces of porcelain that are bonded to the outside of the tooth. They are an excellent choice in many situations. However, frequently they require the shaving or carving down of the outside and in-between surfaces of your teeth. Also known as Instant Orthodontics.
• The fourth choice is using what is called a conventional crown and bridge. There is, in certain circumstances, a very specific need to adopt this technology. Shaving or precision carving down of your tooth is done here as well, to an even larger extent than porcelain veneers. There are nonetheless significant advantages for this technology. There is a far greater control in the manipulation of the “apparent’ location of the teeth. This translates to a greater ability to “move” the tooth from a perception perspective and therefore create a better esthetic result. Even more important than this, again, where indicated, there is less flexure of a tooth with a porcelain crown than a porcelain veneer.

Sometimes small and unattractive teeth go hand in hand with open spaces. In this case a persons smile looks “timid”. The treatment of this problem would be to increase the size of the teeth by placing veneers on top of them closing the Diastema at the same time, leading to a more vivid and healthy smile.

The researchers at the University of Alberta in Edmonton filed patents earlier this month in the United States for the tool based on low-intensity pulsed ultrasound technology after testing it on a dozen dental patients in Canada.

“Right now, we plan to use it to fix fractured or diseased teeth, as well as asymmetric jawbones, but it may also help hockey players or children who had their tooth knocked out,” Jie Chen, an engineering professor and nano-circuit design expert, told AFP.

Chen helped create the tiny ultrasound machine that gently massages gums and stimulates tooth growth from the root once inserted into a person’s mouth, mounted on braces or a removable plastic crown. The wireless device, smaller than a pea, must be activated for 20 minutes each day for four months to stimulate growth, he said.

If you have the space treated with techniques below, it is especially important to have it done by an expert cosmetic dentist. This work is done freehand, and requires artistry, a strong knowledge of composite bonding materials, and meticulous attention to detail. The risks of treatment for diastema (teeth gap) are those involved with any orthodontic treatment.
