Is Tooth Wear Good For Us?

Tooth wear is considered a bad thing in the modern era. It can be painful and unsightly. Furthermore, a 2019 analysis of 706 studies involving tooth wear associated it with sleep disorders, oro-facial pain, oral dryness, GERD, and sleep bruxism (tooth grinding). However, several lines of research conclude that tooth wear, even in childhood, may be an evolutionary survival strategy. Especially as it pertains to proper jaw growth. The story is a little complicated, so I want to give you a little background and then explain how tooth wear may have been beneficial during our evolution.

Protein, Energy, and My Curious Case of Starvation (Or What Human Evolution and History Taught Me)

We can produce glucose from the protein we ingest in the absence of fat and carbs in the diet. Making glucose from protein is a process known as gluconeogenesis. The problem is that our ability to synthesize glucose from protein is very limited and will not sustain us longterm. Luckily, we have such an abundance of food today, most people will never have to rely on gluconeogenesis, except for me. Today, I would like to share my story and put the knowledge I gained from my experience into the larger framework of human evolution and biology.
