The Queen Mother was regularly seen in public until before her death. And the public has noticed how discolored and unpleasant her teeth were.

But even if this was the case, Queen Elizabeth’s mom was still dubbed the Smiling Duchess. The moniker actually had nothing to do with the late royal’s set of teeth. It was given to her because of her strong character.

However, netizens still couldn’t help but wonder why the Queen Mother never had her teeth checked by the dentist. After all, she was a public figure and was oftentimes photographed with the other members of the royal family.

While speaking with Express, dentist Matthew Rose said that the mom of two must not have visited a dentist when she was still alive because during her era dentistry was completely different from what it is today.

“Dentistry was more invasive as mainly comprised of extractions if a tooth presented with a problem, and the preventative side we are all familiar with now such as fluoride was not known about. Modern cosmetic dentistry with its bright white smiles was simply not available to The Queen Mother for the majority of her life,” he said.

Rose went on to say that even though dental work was available for her much later on in life, the Queen Mother must have not given care regarding the appearance of her teeth. In fact, she always smiled beautifully and confidently in public.

Meanwhile, the other members of the royal family seem to be very particular with their teeth. In fact, Rose said that Prince William immediately had work done after he lost a tooth at his friend’s wedding five years ago.

“Post 2014 when it was rumored that he lost a tooth, the upper right central incisor (UR1) looks lighter, and more aligned - as do the upper lateral incisors. It looks to me as if these teeth have been either crowned or veneered,” he said.
