Teeth are covered in a layer of enamel, which is the hardest substance in our bodies. However, that doesn't make them invincible. I cringe when I see someone use their front teeth to bite off a tag. Use a scissors! We often abuse our teeth, but more frequently, front teeth chip a little bit at a time, due to our natural chewing movements when teeth hit each other, clenching and grinding habits (we may not even be aware we have). A back tooth will usually lose a cusp when it fractures. Solutions range from the very quick, smooth the rough edge, to needing to rebuild the tooth with a crown. It is best to not wait until your chipped or fractured tooth hurts, because then you are likely looking at more involved, and costly dental treatment.
