The process of fossilization is a slow one that usually takes thousands of years. In the case of shark’s teeth, they are preserved through a process known as permineralization. Which occurs as water seeps down through the sediments and over the teeth.Shark teeth buried in sediments absorb surrounding minerals, turning them from a normal whitish tooth color to a deeper color, usually black, gray, or tan. The fossilization process takes at least 10,000 years, although some fossil shark’s teeth are millions of years old!Their “adult” teeth will start to appear right around your child’s fifth birthday and, if you teach them at an early age how to take good care of them, can last them their entire lifetime. However, sometimes a permanent tooth will start to erupt while the primary tooth is still present. This is known as shark teeth.
