Autism and the Dentist

Greetings Earthlings! ๐Ÿ™‚

This week I’m going to discuss an important issue for many people on the spectrum- going to the dentist.

I know- no one ever really enjoys going to the dentist (except maybe Bill Murray in ‘Little Shop of Horrors‘! ๐Ÿ˜› ), but for autists in particular, visits to the dentist can be quite traumatic. For many, the invasion of space can be an issue, for others, a trip to the dentist can aggravate sensory sensitivities (the sensation of brushing, the taste of toothpaste, the smell of latex gloves etc).

Thankfully I have never had any major issues with going to the dentist (aside from one unpleasant incident where the anesthetic didn’t take and I felt the drill hit a nerve…), nevertheless it wouldn’t be one of my favourite activities. The high pitched squeal of the tools, the scraping sensation against my teeth, the needles (shudder!)- it’s not the most pleasant of experiences inside my head! There’s a lot of fist clenching! ๐Ÿ˜›

So how might we navigate an autists difficulties at the dentist?

Here are just a few tips and tricks that might benefit parents, dentists and autists alike:

  • Inquire if your dentist is autism friendly– Have they had autistic patients before? Do they have any special tools or techniques to make the visit more comfortable? Do they take any sensory interventions such as dimming the lights, providing sunglasses or minimizing any loud noises that may startle the child?
  • Prepare for a dental visit– Help to desensitize an autist to the experience by story-boarding a trip to the dentist with them so that they know what to expect. When it comes to anxiety, the fear of the unknown is often greater than the reality of the experience. Why not inquire if your dentist will allow you to visit the surgery/send pictures to desensitize your child to the environment and meet the staff before coming in for the real thing? ๐Ÿ™‚
  • Wear noise cancelling headphones– whilst this may not be as effective as in other situations given that the tools are operating so close to the ears, nevertheless this may help to take the edge off any noise related issues.
  • Weighted blanket– A weighted blanket sitting on your lap could be quite beneficial in calming an autist. As I’ve discussed previously, the deep pressure stimulation can calm the mind and put the autist at ease. X-ray jackets can also be used to substitute for a weighted blanket. Comforters such as soft toys or other sensory items that autists use to ‘stim‘ can also be useful to help put them at ease.
  • Communication is key– as I’ve said above, the unknown is often one of the more unsettling aspects of a dental visit for an autist. Talk them through each step, show them what you are planning to do to their teeth, allow them to see and feel the tools- testing a motion on the hand can be useful to desensitize an autist prior to the oral exam.
  • Rewards and Bribery– what child doesn’t love a good bribe to motivate them to get through their dental appointment?! There’s a lot to be said for the power and promise of a treat (I may have even bribed myself with a trip to the cinema to motivate me to get this post finished on time! ๐Ÿ˜‚)
  • Sedation– though not the best of options, this can sometimes be the only way for particularly anxious autists or those with gagging issues to get through a visit to the dentist.

I’ve also found this useful video about visiting the dentist if you want to check it out:

So there we have it Earthlings! I hope you’ve found this post useful ๐Ÿ™‚

Dental care isn’t always the easiest for an autist, but remember, prevention is always best- so get try to find a toothpaste that you like, pick the right toothbrush (soft bristles can be helpful) and take care of those pearly whites! ๐Ÿ™‚

Autism and Taste

Greetings Earthlings! ๐Ÿ™‚

As we have discussed in previous posts (such as sensory issues,ย light sensitivity andย sound sensitivity), people with autism are highly sensitive on a sensory level, so naturally, taste is no exception.

Many autists have highly sensitive taste buds wherein we find a number of flavours and foods too strong and overpowering to tolerate. This sensitivity to tastes can make life very difficult when it comes to taking medicines, food selection (which we will discuss in greater detail at a later stage) and maintaining a somewhat neutral expression when put in awkward public tasting scenarios (perhaps one of my biggest personal challenges ๐Ÿ˜› ).

On the other hand, some autists can in fact be hyposensitive to taste, often preferring foods with stronger flavours

So what’s causing these alterations in tongue sensitivity?

The research into this aspect of autism is currently quite limited, however, some neurological studies indirectly suggest that there is evidence of taste dysfunction in autism.

Many studies have shown evidence of brainstem dysfunction in the neurodiverse brain such as hypoplasia, or under development of the facial nerve nucleus (a collection of neurons in the brainstem that innervate the face). This nerve network carries taste information from the tongue and relays it to the brain. Any dysfunction or damage to this pathway can affect a persons ability to detect tastes.

Furthermore, the ability to identify tastes and flavour perception is controlled by a complex nerve network involving several different brain regions such as the thalamus, insula/operculum, the orbitofrontal cortex (OFC) and our old friend the amygdala. Many of these regions have been implicated in autism, suggesting that dysfunctions in these regions may influence an autists taste buds.

Recent evidence also suggests that autists may be more sensitive to bitter tastes due to genetic mutations in the TAS2R38ย tasteย receptor. Alterations in theย TAS2R38 gene can cause autists to perceive bitter tastes differently to their neurotypical peers which could explain why our taste buds are so sensitive (and why alcohol makes me gag ๐Ÿ˜› )

Finally, an increased sensitivity to smell also feeds into these alterations in tasteย which I will examine next week ๐Ÿ™‚

Until next time Earthlings! ๐Ÿ™‚
