Your teeth do a lot of work across a lifetime: chewing, biting, grinding, and being exposed to everything you eat and drink. It makes sense, then, that tooth wear over time is something almost everyone experiences to some degree, even with good oral hygiene. What changes is how noticeable it becomes, and how much support your teeth might need to keep functioning well as the decades go by.
The pattern of wear you see in your 20s isn’t the same as what tends to show up in your 60s. Broadly speaking, most people move through a few recognisable stages over time:
None of this means wear is something to panic about. It’s a normal part of having teeth. The goal is simply understanding what’s happening so you and your dentist can manage it well.
Dentists generally group tooth wear causes into three overlapping processes: erosion from acid, attrition from tooth-to-tooth contact, and abrasion from physical rubbing, such as brushing.
According to the Australian Dental Association, tooth structure that’s worn away by these processes can’t grow back on its own and typically needs to be managed with treatments like fillings or crowns once it becomes significant.
A few common daily habits tend to be behind most of the wear dentists see, so it’s worth knowing what to look out for:
Wear tends to be mild and gradual at this stage. Most people notice little more than slightly softened edges on their front teeth, particularly if they drink a lot of soft drink, coffee, or sports drinks. Diet and hydration habits formed now can have a real effect on how your teeth look decades later, which is why small changes, like rinsing with water after acidic drinks, can be worth building into your routine early.
This is often when wear becomes more visible, particularly on the biting edges of the front teeth or the chewing surfaces of the back teeth. Stress-related grinding tends to become more common in this age bracket too.
Many people don’t realise they grind or clench until a partner mentions the noise, or a dentist spots the wear pattern at a check-up. Teeth grinding, known as bruxism, can be caused by stress, sleep issues, or an uneven bite, and it can accelerate wear considerably if it isn’t managed. A properly fitted night guard is one of the more common ways dentists help protect teeth from further damage.
Ageing and enamel wear tend to go hand in hand, simply because enamel has had more decades of exposure to work with. Gums can also recede over time, exposing the softer root surface underneath, which wears more easily than enamel and can be more sensitive to hot or cold. F
or some patients, decade by decade dental changes eventually mean missing teeth need to be addressed, whether through a bridge, an implant, or dentures, depending on what’s suitable for their individual situation.
A quick note: how much wear shows up, and how quickly, depends on your individual habits, genetics, and dental history. Two people the same age can have quite different amounts of wear, so treatment suitability depends on individual circumstances rather than age alone.
Keeping an eye on tooth wear over time is mostly about consistency rather than anything complicated. A few habits make it easier for you and your dentist to catch changes early:
Wondering what causes enamel to wear down in the first place? Our page on dental erosion causes covers this in more depth.
Mild wear often just needs monitoring. More significant wear may be suitable for treatments such as a dental crown to protect and rebuild a tooth’s shape, particularly if the wear is affecting how comfortably you bite or chew.
Healthdirect notes that teeth grinding can cause enough damage to warrant a dental visit if you’re experiencing facial pain or poor sleep alongside the wear. Your dentist can talk you through whether treatment may help in your specific case, since results vary between individuals.
Yes, some tooth wear over time is expected and considered a normal part of ageing. How much wear you experience and whether it needs treatment can vary between individuals depending on habits, diet, and dental history.
In many cases, yes. Depending on the extent of the wear, options like crowns or other restorative treatments may be suitable. A dentist would need to assess your teeth first, since suitability depends on individual circumstances.
Grinding can speed up wear considerably compared to everyday use alone. If you suspect you grind your teeth, it can help to mention this at your next check-up so your dentist can assess whether a night guard or other option may be suitable for you.
Most patients benefit from a check-up roughly every six to twelve months, though your dentist can advise what’s appropriate for your situation, since needs vary between individuals. Patients across Launceston, including Invermay and Riverside, are welcome to book a check-up to have their wear assessed.
Not entirely, since some wear is a natural part of using your teeth over a lifetime. However, habits like limiting acidic drinks, using a soft-bristled brush, and managing grinding may help slow it down. Results can vary between individuals depending on genetics and daily habits.
