What is Sensory Food Aversion and Oral Defensiveness?


Food is an essential aspect of human life, providing us with vital nutrients and energy to survive and thrive. However, for some individuals, eating can be a challenging and distressing experience. Sensory food aversion and oral defensiveness are two conditions that can affect an individual's ability to eat and enjoy a wide range of foods.

You know your child is a picky eater. And after reading the last article on picky eaters, you know your child has some sensory food aversion to certain textures. But what do you do about it?

Sensory food aversion refers to a strong dislike or avoidance of certain tastes, textures, smells, or appearances of foods. Individuals with sensory food aversion may find it challenging to eat a varied diet or may only consume a limited selection of foods that they find palatable.

While, oral defensiveness is a hypersensitivity to touch or texture in the mouth, which can result in discomfort or avoidance of certain foods. They are different than picky eating!

Oral defensiveness can occur in children who also have tactile defensiveness. Both types of defensiveness are part of sensory processing disorder.

These conditions can affect individuals of all ages, from infants and toddlers to adults. Sensory food aversion and defensiveness to oral input can have a significant impact on an individual's physical health, mental well-being, and social interactions.

In this article, we will explore these conditions in more detail.

What are sensory food aversion and oral defensiveness?

Oral defensiveness is when a person has an aversion to certain textures, tastes, smells, or temperatures of food. This can make eating difficult and even painful for some people. Oral defensiveness can be caused by a variety of things such as sensory processing disorder, food allergies, or autism spectrum disorder

How do I know if my child has a sensory food aversion and is orally defensive, or just stubborn?

There are a few signs that may indicate that your child is orally defensive. If your child gags, chokes, or throws up when eating, this may be a sign that they are orally defensive.

What can I do to help my child with oral defensiveness?

If you think that your child may be orally defensive, there are a few things that you can do to help them. One thing that you can do is consult with a doctor or therapist who specializes in sensory processing disorders or feeding disorders. They will be able to give you specific guidance on how to best help your child.

Another thing that you can do is work on exposure with your child. This means gradually introducing new foods and textures to them in a non-threatening way. 

You can start by letting them touch or smell the food before moving on to taking small bites. It is important to go at your child’s pace and not force them to eat anything that they are not comfortable with.

If your child is still eating baby food and they are having a hard time when eating purees. I recommend making your own food. You can vary the thickness and gradually increase it over time.  And the added benefit of the purees tastes like real foods.  

Causes of Oral Defensiveness in Children

There are a number of reasons why a child is orally defensive to sensory input. Some children are born with a sensitive gag reflex, which makes them hesitant to put new things in their mouths.  Or they may have had a medical condition at birth such as a genetic condition or prematurity, which led to being tube fed.  Lack of food or objects in a baby's mouth can increase sensitivity later on.

Dealing with Oral Defensiveness in Children

If your child has sensory food aversion, it is best to have them evaluated by their dr, an occupational therapist who is experienced in working with children with a sensory processing disorder, or a feeding clinic. They should also be evaluated for oral motor difficulties such as chewing and swallowing.

The same suggestions for navigating picky eaters apply to those with oral defensiveness. However, also remember that the issue your child has is with the food TEXTURES of certain foods. 

First, try not to force your child to eat anything they're not comfortable with. This will only make them more resistant and less likely to want to try new things.

Second, offer other foods that are similar in texture to the ones your child already eats. For example, if your child likes strawberry yogurt offer them other yogurt flavors. 

Third, make mealtimes fun and relaxed instead of stressful. This will create a positive association with food and make your child more likely to want to try new things. 

Fourth, Always offer safe, preferred foods along with the foods you are eating.  Putting new foods within reach or on their plate but do not force them to be eaten. But don't assume they won't want to eat the new foods either!  Keep offering!

Finally, be patient and offer encouragement. It may take some time, but eventually, your child will hopefully outgrow their oral defensiveness with the help of pediatric occupational therapy, and be open to trying new foods.

Final Thoughts

Oral defensiveness can be frustrating for both parents and children alike but there are ways to overcome it. If you think your child may be orally defensive, the first step is to consult with a doctor or therapist specializing in sensory processing disorders or feeding disorders. 

Additionally, you can work on exposure with your child by gradually introducing new foods and textures in a non-threatening way. Going at your child’s pace and not forcing them to eat anything will also be helpful in overcoming oral defensiveness.
