Weak Teeth Symptoms – Causes and Treatment

Have your teeth started to wear down? Unfortunately, it’s not uncommon for teeth to show signs of wear and tear, particularly as we age. However, if you want to look out for your long-term oral health it’s important to be aware of what causes teeth to wear down and in particular weak teeth symptoms. But before we dive into specific causes and dental crowns as one of the treatments for weak teeth, we need to talk about tooth enamel.


The importance of tooth enamel

Tooth enamel is the hard outer surface that covers the teeth and its role is to protect against substances that can harm the teeth such as sugar and acids. It’s also the hardest mineral in the human body, even stronger than bone.

Unfortunately, tooth enamel contains no living cells, so should damage occur from a chip or fracture, then unlike other tissues, it can’t repair itself.

In other words, once tooth enamel has gone, it’s gone for good and this can leave a tooth weak and vulnerable to decay.

So now you understand the importance of tooth enamel and the effect it can have on your oral health, let’s take a closer look at 5 elements that can weaken teeth. 


Your diet 

The food you put in your mouth each day has a significant effect on tooth enamel. Foods that contain a lot of starch such as white bread and potato chips can linger in the mouth and produce acid, while sugary snacks – especially chewy ones – can damage the enamel. The best defence against enamel erosion is to eat a calcium-rich diet that can strengthen your teeth. 


Soft drinks

Soft drinks can be particularly harmful to tooth enamel and oral health, especially if you reach out for them daily. Soft drinks contain high levels of phosphoric and citric acids which cause damage to the enamel. Fruit juices can also be harmful because they contain acids. 



According to a recent news publication, certain genetic diseases influence the development of cavities and periodontal disease. A genetic disorder known as “amelogenesis imperfecta” is responsible for defects in the enamel that affect the appearance of the teeth. They can be small and/discoloured or be pitted with grooves in the surface of the enamel. Patients with this genetic disorder are prone to weak teeth with symptoms such as rapid wear and breakage. 



This refers to a loss of tooth structure where the teeth and gums meet. The damage is usually shaped like a ‘V’ or wedge-shaped and has no relation to cavities, infection or bacteria. 

While abfractions are usually painless, they can cause tooth sensitivity and discomfort which can sometimes be relieved by filling in the spot with a composite. 



Teeth grinding (bruxism) refers to the friction caused when people grind or clench their teeth. While this often occurs during the night when they’re asleep it can also happen during the day. Persistent teeth clenching or grinding causes the enamel to wear down so most dentists will prescribe a custom mouthguard to wear over the teeth to prevent further damage. Bruxism sufferers may also experience jaw pain as well as tooth sensitivity. 

So now you know some of the causes let’s take a look at some of the symptoms of weak teeth

Depending on how far your teeth have weakened, symptoms include 

  • Cracks and fractures
  • Tooth sensitivity
  • Tooth discolouration

Patients can help ease their symptoms by avoiding acidic foods, switching to a toothpaste for sensitive teeth, and reducing their stress levels. It’s also best to visit a dentist who can offer a variety of treatments, including dental crowns, to help with the associated sensitivity or discomfort. 


Dental crowns – Treatment for weakened or worn teeth 

Dental crowns are an extremely versatile treatment that can be used to protect and strengthen teeth that have weakened while also helping to maintain oral health. 


What is a dental crown?

A crown is a cover or ‘cap’ that’s customised to fit over a patient’s tooth. Typically it restores the shape and size of a tooth, enhances its performance, and improves its aesthetics. Once cemented into place, it offers full protection for the tooth. 

Here are 3 of the most common scenarios when a dental crown may be used to help teeth that have become weak or worn. 


Following root canal treatment 

Root canals are typically required when the inner pulp of a tooth has been infected and involves removing the infected material, flushing out the canals, and filling the tooth. Because this procedure can often leave teeth weak dental crowns are used to strengthen the structure and provide support. Symptoms that a root canal may be necessary include persistent discomfort, swollen gums and sensitivity to hot and cold temperatures. 


When a tooth is close to breaking

Cracks and fractures in the teeth raise the risk of breakage. They can also cause tooth sensitivity. Placing a crown over the affected tooth gives instant relief from discomfort and makes the tooth stronger. 


For cosmetic reasons

If a tooth has become discoloured, the tooth enamel has worn, or the lower edges of the teeth are uneven and ragged due to tooth grinding, then dental crowns offer a solution by restoring aesthetics, strength and functionality. 


How long do dental crowns last?

Typically, however, dental crowns should last anywhere from 5 to 15 years.

The most important factor in ensuring the longevity of your dental crowns is to maintain good oral health. This includes brushing and flossing every day and regular dental check-ups.
