Episode Summary:
02:07 – Why is nail biting such a big problem for your teeth?
Dr Clifford Yudelman – OptiSmile:
Nail biting seems harmless, but it wears down and cracks your front teeth, which aren’t designed to act like nail clippers. Over time, it creates tiny fractures—much like hitting a porcelain cup with a spoon every day. The repetitive trauma builds up into costly damage, especially when biting cuticles, which worsens wear patterns and inflammation.
03:39 – What kind of damage can it cause over time?
Dr Clifford Yudelman – OptiSmile:
Teeth develop micro cracks and chips, particularly on the incisal edge (biting edge). Wear increases and teeth may shift subtly. Because the teeth continue erupting, wear often goes unnoticed. Nail biters may eventually require Invisalign or restorations. Composite bonding and veneers are at risk of breakage from this subtle, constant pressure.
05:07 – Are there risks to the gums or jaw as well?
Dr Clifford Yudelman – OptiSmile:
Yes—nail fragments can lodge under gums and trigger infections. If there's existing gum disease, repeated trauma can lead to loosened teeth or bone loss. Biting motions also strain the jaw joint (TMJ), especially when patients bite at an angle, unknowingly exacerbating muscle tension and joint misalignment.
06:36 – Can nail biting affect cosmetic dental work like Invisalign or veneers?
Dr Clifford Yudelman – OptiSmile:
Absolutely. Micropressure can shift Invisalign-treated teeth over time—even with retainers. Veneers, especially porcelain ones, are strong but thin and vulnerable to edge chipping. Composite bonding also chips easily when patients forget and resume nail biting. OptiSmile warranties some work, but not when habits continue repeatedly.
08:06 – Is nail biting linked to stress or anxiety, and do people realise they’re doing it?
Dr Clifford Yudelman – OptiSmile:
It’s often subconscious and triggered by stress, boredom, or anxiety. Patients usually only notice the consequences—bleeding cuticles, short nails, chipped teeth—not the behaviour. It often starts in childhood and can even run in families. Once established, it becomes an automatic habit that’s very difficult to break.
09:51 – Can a manicure help stop the habit?
Dr Clifford Yudelman – OptiSmile:
Yes. Both men and women benefit from grooming. Spending money on well-maintained nails discourages biting. It’s also important socially—chewed fingers and chipped teeth can make you look older, nervous, or unprofessional in settings like job interviews.
11:05 – Are there general health risks from putting your fingers in your mouth all the time?
Dr Clifford Yudelman – OptiSmile:
Definitely. Nail biting increases your risk of bacterial and viral infections. From norovirus and E. coli to COVID, hands pick up germs from doorknobs, phones and escalators. Biting your nails is a direct transmission path into your mouth. Additionally, oral bacteria can infect open wounds around bitten nails, creating a two-way infection route.
12:55 – How can someone tell if nail biting is already causing dental damage?
Dr Clifford Yudelman – OptiSmile:
Check your front teeth in bright light (like your car’s rearview mirror). Look for ragged edges, chipping, hairline cracks or sudden sensitivity when biting into food. If your dentist asks, “Are you biting your nails again?”—it’s probably visible. Also, look for short nails, ridges or small infections near the cuticle.
14:17 – What practical tips actually work to help someone stop?
Dr Clifford Yudelman – OptiSmile:
Awareness is key. Bitter nail polishes help condition the behaviour. Stress management—therapy, fidget toys, mindfulness—can address triggers. Regular manicures, keeping nails short, and setting personal rewards can also help. One unique tip: snap a thick elastic band on your wrist whenever you catch yourself doing it—negative reinforcement works for many.
17:02 – When should someone visit a dentist, and how can OptiSmile help?
Dr Clifford Yudelman – OptiSmile:
If you notice chips, sensitivity, or wear—book a check-up. OptiSmile offers edge bonding, custom splints, and Invisalign to correct misalignment. Injection-moulded bonding is a cost-effective and repairable alternative to veneers. In persistent cases, we may recommend retainers or daytime splints to protect enamel and discourage the habit.
19:39 – Final advice to nail biters?
Dr Clifford Yudelman – OptiSmile:
Nail biting is a small, unconscious habit that leads to major dental problems. Stopping now can prevent thousands in dental bills. Your teeth are for smiling and chewing—not grooming. Try bitter polish, carry a stress ball, or use the elastic band technique. Protect your smile, and your wallet, by kicking the habit early.
