Gaps in the incisors can be corrected, usually only with orthodontic braces to close the gaps in the teeth. If the gap in the teeth is caused by decay, it is recommended to grind away the decayed matter and then just fill it with resin to finish it. If it is not due to decay, but simply the gap of teeth, you can use resin to do dental veneer, also can close the gap of teeth, aesthetic resin is generally better color, can achieve the aesthetic requirements, but there is a long-term possibility of resin coloring or cracks, in general, do porcelain veneer is the best. If the tooth gap is large or tooth decay is relatively large, then you can do porcelain full crown restoration, the tooth will be worn around the small, do porcelain full crown bonding with the surface of the tooth, more beautiful, and more long-lasting. If there is a gap in the incisor and the tooth is loose, it is recommended to remove the affected tooth for treatment, and then carry out implantation or porcelain crown bridge restoration, grinding the adjacent teeth smaller, and then make three or four connected crowns, the aesthetic effect is very good.
