Renowned cosmetic dentist and founder of Bespoke Smile, Dr. Sam Jethwa, based in London, highlights that while some snacks may be more apparent than others, certain ones can significantly impact dental health.

These particularly harmful culprits have the potential to stain teeth, erode enamel, and even lead to dental fractures.

Here, Dr. Jethwa presents the top five items he strongly advises individuals in Britain to avoid consuming in order to maintain optimal dental well-being.


One popular accompaniment to roast dinners, pork crackling, poses a significant threat to dental health. Despite its crunchy appeal, this side dish can result in the formation of crevices and eventual decay.

Over time, the consumption of pork crackling may lead to tooth sensitivity, discomfort, and the need for fillings. Dr. Sam Jethwa, sharing his insights with MailOnline, explains that while cracks are often attributed to bite problems, they can also be caused by indulging in foods like crackling or biting on unpopped popcorn kernels. To mitigate these risks, he advises avoiding such foods altogether.

Moreover, the particles from these crispy snacks tend to get trapped within the crevices of teeth, ultimately fostering tooth decay as time passes.


Dr. Sam Jethwa also identifies olives as a food that carries the potential for dental damage. Despite being a popular and enjoyable snack, the hidden pits within olives pose a risk to oral health.

Similar to crackling, biting down on a pit can result in the development of cracks in the teeth. It is worth noting that this danger becomes more pronounced as we age, given that our teeth tend to weaken over time.

To safeguard dental well-being, it is advisable to exercise caution while consuming olives and be mindful of the presence of pits. Taking preventative measures can help minimize the risk of dental fractures and related complications.


Turmeric has gained a reputation as a “superfood” due to its anti-inflammatory properties, which contribute to overall health. However, when it comes to dental aesthetics, it is advisable to consume turmeric in moderation if you wish to maintain a white smile.

Dr. Sam Jethwa warns that the vibrant yellow-orange spice, commonly found in curries and milk-based beverages, has the potential to stain teeth the same hue. This staining effect is especially problematic for individuals who have undergone teeth whitening treatments or have porcelain veneers.

Following teeth whitening, the teeth become more susceptible to staining, and although porcelain veneers are typically resistant to turmeric stains, the natural teeth surrounding the veneers can be affected. Consequently, the contrast between the veneers and the stained natural teeth may become more noticeable, compromising the aesthetic result.

To preserve a pearly white smile, it is advisable to limit consumption of turmeric, especially for those who have undergone teeth whitening procedures or have veneers to maintain a consistent and uniform appearance.



Toffees, along with other exceptionally sticky sweets, are a well-known culprit to avoid if you want to maintain optimal dental appearance. Their detrimental effects on teeth are so significant that Dr. Sam Jethwa personally refrains from consuming them altogether.

The high sugar content in toffees, a leading cause of tooth decay, is one obvious reason to steer clear of them. However, their sticky nature exacerbates the problem. Due to their chewy texture, toffees tend to cling to teeth for an extended period, increasing the likelihood of decay.

Moreover, the sticky consistency of toffees can create significant challenges for individuals with dental fillings, crowns, composite bondings, or braces. These sweets have the potential to dislodge or even remove such dental work or orthodontic appliances.

Dr. Jethwa emphasizes that the prolonged adherence of toffees to teeth and the risk of dislodging dental work make them a particularly troublesome treat, warranting complete avoidance for the sake of dental health and preservation of dental restorations.


Dr. Sam Jethwa strongly advises avoiding gobstoppers without hesitation. He emphasizes that gobstoppers have the potential to inflict damage such as cracks, chips, cavities, and tooth decay, making it an easy decision to steer clear of them.

The prolonged and intense chewing required to consume gobstoppers poses a significant risk to dental health. The constant pressure exerted on the teeth during this process can lead to the development of cracks or chips. Furthermore, the high sugar content of gobstoppers contributes to the formation of cavities and tooth decay.

Considering the multiple risks associated with gobstoppers, Dr. Jethwa unequivocally recommends refraining from consuming them entirely. By doing so, individuals can safeguard their dental well-being and reduce the chances of encountering dental problems caused by these hard and sugary treats.
