As part of mum's FTD she has developed a real sweet tooth and is scoffing chocolates and sweets at an alarming rate. Other than the weight gain I'm slightly concerned about how this diet is affecting her health because to be honest her breath smells terrible. I've asked dad about whether she's cleaning her teeth (as it seemed the most obvious answer) but he's certain that she is. It's a strange smell - not dirty teeth smell - but it's really very strong and unpleasant. Could her diet be causing this? Has anyone else experienced this?
