Solon went to his first check-up when he turned 3. He did awesome. It helps that we have a great dentist and hygenist and they have satellite TV - Mickey Mouse Clubhouse, anyone? It was a little humbling when they found an eency weency beginning of cavity in his mouth - I wanted to crawl in a hole because we brush his teeth - MOM FAIL moment! Luckily for us, it was a quick fix with no novicaine required and we have been much more thorough with the back molars ever since (learn from my mistake - brush well those back teeth ;).
