According to various sources, Britney Spears has a gap in her front teeth that she chose not to replace after undergoing dental bonding in the past. Some fans have speculated that her teeth may have shifted due to gum disease caused by smoking and neglect. However, there is no concrete evidence to support this claim. Another theory is that she may have veneers. In recent years, Britney has been seen in photos and videos with her lips pursed, which may be an attempt to conceal her teeth. Overall, the exact reason for the gap in her teeth is not clear, but it appears to be a personal choice.
