At Inima Dental Clinic Marbella, we not only treat visible dental issues, but also raise awareness about harmful habits that can affect the aesthetics, functionality, and health of your mouth.
One of the most common — and often underestimated — habits is onychophagia, or in simpler terms: nail biting.
What Is Onychophagia?
Onychophagia is a compulsive disorder characterised by biting the nails, often triggered by anxiety, stress, or boredom. While it may seem harmless, this habit can have serious consequences for your oral health, in addition to negatively affecting the appearance of your hands.
Consequences of Onychophagia on Oral Health
Many people do not associate nail biting with oral health, but this habit can lead to several dental and functional problems, including:
Tooth Wear
The constant contact between teeth and nails leads to abnormal enamel wear, especially on the incisors, which can result in microfractures and tooth sensitivity.Dental Misalignment
Biting nails applies irregular pressure on the teeth, potentially causing them to shift or worsening existing malocclusion. In some cases, orthodontic treatment may be required to correct the alignment.Gum Inflammation
Bacteria under the nails can be transferred to the mouth, increasing the risk of gum infections, irritation, or even mouth ulcers.Temporomandibular Joint (TMJ) Problems
Repeated strain and clenching can overload the TMJ, causing facial pain, clicking sounds, or difficulty chewing.Higher Risk of Infections
Nails come into contact with various surfaces, potentially carrying viruses and bacteria into the mouth and raising the likelihood of oral or systemic infections.
What Causes Onychophagia?
The causes of onychophagia vary, but it is commonly associated with:
Anxiety or stress
Obsessive-compulsive disorders
Childhood habits
Lack of awareness of its negative effects
How to Stop Nail Biting
Overcoming this habit requires a multidisciplinary approach. At Inima Dental Clinic Marbella, we recommend:
Consulting a mental health professional if the root cause is emotional or psychological
Using bitter-tasting nail varnish to deter the behaviour
Practising good hand hygiene and regular manicures to improve nail appearance
In some cases, wearing dental splints to protect the teeth while addressing the habit
