While most minor flaws in your teeth may not affect your oral health, they can significantly affect the appearance of your smile and your confidence. These types of flaws include: • Minor chips and cracks. • Spaces between your teeth. • Oddly shaped teeth. • Teeth that are smaller than those around them. • Small cavities. Cavities can affect the health of your mouth, in addition to the appearance of your smile, if they are not treated promptly.
