Do dental sealants need to be reapplied?

In most cases, a cracked tooth can’t be seen on an X-ray, but it is still needed to look for decay and nerve pathology. READ MORE
What do sealants do?
Teeth form from multiple parts and those fuse together leaving grooves. These grooves go deep into the tooth where the toothbrush can’t reach. The sealants seep into these grooves so food and bacteria can’t thus preventing cavities. Stephen Lashen READ MORE
