Unfortunately, the likelihood is that we can all find something in this list that we are guilty of. Now is the time to realise and knock it on the head before it becomes something that could be damaging.
These things can be as simple as trying to give yourself a bit of a health and immune system boost in the morning. You can't do right for doing wrong, can you?
Let me explain.
If you, like many others, have followed the example of health-conscious celebrities such as Victoria Beckham and Gwyneth Paltrow, and started taking a glass of hot water and lemon every morning, you might be doing yourself an unseen mischief right there.
According to Dr Christopher Orr, who is the head of the team over at Advanced Dental Practice in London, this is the biggest cause of tooth erosion amongst middle-aged women these days.
He told FEMAIL: "We are now seeing patients in their 50s and 60s coming to us for treatment for damage caused by citric acid.
"The irony is that hot water and lemon has replaced the morning cup of tea and coffee because of this perception that it's healthier and leaves you feeling cleansed and refreshed, however tea and coffee are pretty close to neutral in terms of acidity and are less damaging from a tooth point of view."
Stick with a nice brew, then.
If it ain't the lemony water that gets you, it's likely to be something else though. Who among you starts the day with a lovely piece of fruit?
Yep, even that could be problematic.
Fruit is - of course - full of sugar. Sugar - of course - decays the teeth.
It doesn't end there, either.
Everything from vaping, which could bad if you're vaping a sugary e-liquid, or ditching a plastic straw, which exposes the teeth to carbonated or sweet drinks, could be causing tooth decay.
It bears repeating - you can't do right for doing wrong.
Chewing on pens at work? Seems like an obvious one, but we all do it. It can chip your teeth, or cut your gums.
Even brushing your teeth, if done too hard, can cause damage to teeth and gums.
So, there you have it - even if you're a lemon tea drinking non-smoker who brushes their teeth twice a day, you're potentially still at risk of damaging your teeth.
Add into that the fact that you might be grinding your teeth or clenching your mouth in your sleep - or at least, you might after this - and there's a lot to be working on there if you want to stay out of the dentist's bad books.
