Well-being Toolkit for Dental Professionals launched to coincide with World Mental Health Day

This World Mental Health Day (Monday 10th October 2022), Dr Mahrukh Khwaja, dentist and positive psychologist, together with Unilever’s oral care brand Zendium, launch a new, activity-based Wellbeing Toolkit to help address the mental health challenges within dentistry

Dentistry is a high-stress profession with elevated rates of anxiety, depression, burnout, suicidal thoughts and self-harm.1,2 Unsurprisingly, the pandemic has magnified these negative feelings. In the recent Dentistry Census 2022, 68% of dental professionals felt that their relationships, both within the clinic and at home, suffered as a result of work-related stress, with over 30% of dental professionals saying they felt routinely depressed. Dentist and Positive Psychologist, Dr Mahrukh Khwaja, has been a leading light on this topic since her own experience with depression and burnout in 2016. “As dental professionals, we spend so much time caring for our patients, it can be easy to neglect ourselves. It wasn’t until I experienced my own well-being challenges, that I really appreciated the importance of becoming the architect of my own mental health, and I started using tools and activities that nourished, restored, and revived me.”

“There are evidence-based techniques that can be utilised to help dental professionals not only cope with stressors, but to move beyond baseline to optimal states, such as flourishing,” continues Dr Khwaja.  Chief among these strategies is the PERMA-H model, which focuses on six components of well-being to help people feel happier, energised at work, connected to others, have a sense of purpose and accomplish goals aligned to their values. “Whilst these psychological tools on their own won’t solve the mental health crisis in Dentistry, they will go a long way in prevention and help dental professionals develop the necessary skills of resilience and positive health.”

The oral care brand Zendium, from Unilever, champions a holistic approach to mouth health, and this translates to a similarly holistic view of how it can support the dental community. Together with Dr Khwaja, Zendium has created a practical, activity-based Wellbeing Toolkit for dental professionals, based on the PERMA-H model, which helps people nurture and boost their mental health.  Monika Fleischhacker is Unilever’s Director of Oral Care Professional Marketing: “We know how important it is to support the dental community beyond oral care products themselves, and we know that the last two years in particular have been very challenging for all medical professionals. We’re hugely proud to have been able to work with Dr Khwaja to help address the mental health issues in dentistry in a very practical way.”

Dr Khwaja continues: “The Well-being Toolkit for Dental Professionals can be thought of as a self-intervention: your guide to help you integrate the different ingredients of well-being, and increase positive feelings, positive thoughts and positive actions in the process,” says Dr Khwaja.

Could SLS toothpastes be irritating some patient’s mouths?

As the consumer demand increases for mild formulations and gentle ingredients, it is important for dental professionals to be aware of the ingredients typically found in toothpastes and mouthwashes and furthermore products that offer whole mouth protection without the need for harsh formulations.

This is especially topical as the desire for sulfate-free substitutes has been rapidly increasing among consumers. Research from Google reveals a 180% increase in searches for ‘toothpaste without sodium lauryl sulfate’ in the UK within the past 12 months (June 2020 – June 2021).

While Sodium Lauryl Sulfate (SLS) is a safe ingredient and not harmful, in the last 2 years there has been a 20% increase in products claiming to be SLS free. This trend has gained a lot of popularity in all kinds of products especially shampoos as SLS is believed to dry out hair and strip away the colour. There has also been a rise in body washes, soaps and face cleansers, which are now “sulfate-free” as some find that SLS, can dry out and irritate their skin.

SLS is used in most toothpastes to create the foam associated with being ‘squeaky clean’, but does this ingredient have the potential to irritate the tissues in patients with delicate oral mucosa?

What is SLS?

SLS or Sodium Lauryl Sulphate is a chemical agent that is used for cleaning. It is the most commonly used detergent in the beauty industry, and essentially helps liquid substances “foam”.

It was originally developed in 1930 for the laundry industry to clean your clothes, and the sulfate craze quickly became popular in a lot of products, specifically within the Beauty & Personal Care category. It is now found in many everyday cleaning products from floor cleaners to shampoos and toothpastes.

What is the difference between SLS & SLES?

Some people confuse Sodium Lauryl Sulphate (SLS) with its sister compound, Sodium Laureth Sulphate (SLES), which is also frequently used as a foaming agent in toothpastes, shampoos, body washes and face washes. SLES is a milder version of SLS, so is not as irritating but the important thing to remember is that products claiming to be SLS-free usually mean they are free of both compounds.

What relevance does this have for our mouths?

Nearly every toothpaste contains surfactants, which help to create the foam that loosens debris and makes cleaning easier when you brush – this is the effect of SLS. Another effect of SLS is the distortion in taste we experience after brushing. While this can upset the taste of your morning coffee or orange juice, the majority of us don’t experience any side effects from having SLS in our toothpaste. However, oral tissues are delicate, and some research from the British Dental Journal and NCBI have shown this ingredient could be an irritant to some patients mouths and can even cause “oral mucosa peeling.” Stripping away the delicate layers of the oral mucosa[1]. However, it should be noted there is no evidence whatsoever that the small amounts of SLS present in toothpaste can cause any long-term health effects. It is a safe ingredient when used minimally, however there is a specific group of patients who may be more sensitised than others.

Patients with a delicate oral mucosa are more likely to find SLS containing toothpastes less suitable, especially those with aphthous ulcers as Sodium Lauryl Sulphate toothpaste can increase the frequency of repeated mouth ulcers.[2] Those who suffer with a dry mouth may also benefit from SLS free toothpaste and it can also be too harsh for pregnant women and even young children whose mouths are more sensitive. I personally had a patient who suffered with dry mouth consistently and complained of a “stinging sensation” after she would brush her teeth. After long conversations and careful investigation, I recommended her to try and switch to an SLS free toothpaste, Zendium, and she was over the moon about how much better her mouth felt after only 2 weeks.

What are the benefits of an SLS free toothpaste?

Choosing SLS free toothpaste can be beneficial to those with more vulnerable mouths. A clinical study published in the Journal of Dentistry measuring soft tissue lesions on the oral epithelia demonstrated that there were 4x fewer lesions after 30 minutes when using Zendium toothpaste which is SLS free compared with a toothpaste containing SLS.[3] A balanced microbiome is also crucial for oral health to protect us against oral disease and Zendium has been shown to shift the oral microbiome towards a healthier state.

Zendium is a daily fluoride toothpaste which has been specially designed without Sodium Lauryl Sulphate (SLS). Instead, it contains a mild, low-foaming agent called stereath-30, which protects the delicate soft tissues of the mouth. It also helps to maintain the activity of the enzymes and proteins in Zendium toothpaste which are clinically proven to boost good bacteria in the mouth to improve the balance of the microbiome[4] and protect against dental problems. It can be used for those patients who have a delicate oral mucosa and for the everyday patient too. I personally use it twice daily!

Is SLS free toothpaste as effective?

For years, brushers thought that their toothpaste needed to foam to be effective. But toothpastes don’t need to contain SLS in order to effectively clean all surfaces in the mouth. A foamy feel can give the perception of a cleaner mouth and can make it easier to spread toothpaste around, but it is possible to clean the mouth just as effectively using an SLS-free toothpaste.

The SLS free trend is rapidly growing, including in oral hygiene products. Although SLS is safe, some can find regular toothpastes with SLS uncomfortable to use and benefit from switching to a toothpaste which is SLS free.  There is certainly no harm in seeking out sulfate free substitutes.

Dentists should be aware of this ingredient and understand the advantages and disadvantages in everyday toothpastes to be able to discuss with patients and be able to recommend suitable products especially for those patients who are more likely to find SLS an irritant.
