Thickened Toenails Treatment

Professional Nail Care & Restoration

Expert treatment for thick, discoloured, and difficult-to-cut toenails at our foot care clinic in Vaasa.

What Are Thickened Toenails?

Thickened toenails (onychauxis) are nails that have become abnormally thick, hard, and often discoloured. They can be difficult or impossible to cut with standard nail clippers and may cause discomfort when wearing shoes.

While thickened toenails are not usually a serious medical condition, they can be unsightly, uncomfortable, and sometimes painful. Professional nail care can restore their appearance and make them manageable again.

Common Causes of Thickened Toenails

External Causes

  • Repeated trauma or injury to the nail (dropping objects, stubbing toes)
  • Tight-fitting shoes pressing on the nail over time
  • Running or sports that cause repetitive impact on the toes
  • Fungal nail infection (onychomycosis) — the most common treatable cause
  • Poor footwear habits over many years

Internal Causes

  • Natural ageing — nails grow slower and thicker with age
  • Psoriasis and other skin conditions affecting the nails
  • Poor circulation (peripheral vascular disease)
  • Diabetes — affects nail growth and healing
  • Genetic predisposition — some families are more prone

Signs & Symptoms

  • Increased thickness — the nail becomes noticeably thicker than normal
  • Discolouration — nails may turn yellow, brown, or whitish
  • Difficult to trim — standard nail clippers cannot cut through the nail
  • Brittle or crumbly texture — the nail may split, flake, or crumble at the edges
  • Curved or deformed shape — the nail may grow in an unusual direction (ram's horn nails)
  • Pain or discomfort — pressure from shoes on the thickened nail
  • Lifting from the nail bed — the nail may partially separate from the skin underneath

How We Treat Thickened Toenails

Our foot care specialists use professional equipment to safely and comfortably manage thickened toenails:

Our treatment process:

  1. Thorough assessment of your nails to determine the cause
  2. Professional nail grinding (burring) to reduce thickness safely and painlessly
  3. Careful shaping and smoothing of the nail surface
  4. Trimming to a proper length and shape
  5. Treatment of any associated skin issues (calluses, corns around the nail)
  6. If fungal infection is suspected, advice on treatment options and referral if needed

Professional nail grinding is painless and brings immediate improvement. The nail looks thinner, smoother, and more natural afterwards. Shoes fit more comfortably right away.

Regular maintenance is key — thickened nails continue to grow thick, so periodic professional thinning (every 6–8 weeks) keeps them comfortable and healthy-looking.

Self-Care Tips

Nail care at home

  • Soak feet in warm water before attempting to trim nails — this softens them
  • Use heavy-duty toenail nippers rather than standard clippers
  • Cut straight across, not curved, to prevent ingrown nails
  • File rough edges gently with an emery board
  • Apply nail oil or moisturiser to the nail and cuticle area daily

Prevention

  • Wear properly fitting shoes with enough toe room
  • Protect toes from injury — wear safety shoes if required at work
  • Keep feet clean and dry to prevent fungal infections
  • Wear moisture-wicking socks and change them daily
  • Treat fungal infections promptly — they worsen over time

What to avoid

  • Never force standard clippers through a very thick nail — they can crack and splinter
  • Do not try to thin nails yourself with files or tools — risk of damage and infection
  • Avoid tight shoes that press on the nails
  • Do not ignore changes in nail colour or texture — they may indicate a treatable condition

When to Seek Professional Help

Visit us if:

  • You cannot cut your toenails with standard clippers
  • Your nails are causing pain or discomfort in shoes
  • Your nails are discoloured, crumbly, or have an unusual smell (possible fungal infection)
  • You have diabetes and cannot safely manage your own nail care
  • Your nails are growing in an unusual shape or direction
  • The skin around the nail is red, swollen, or painful
Important for diabetics: Thickened toenails can press on the skin underneath and cause ulcers that you may not feel due to neuropathy. Regular professional nail care is strongly recommended for all people with diabetes.

Frequently Asked Questions

No, professional nail grinding is painless. The nail itself has no nerve endings, so you feel only a gentle vibration and warmth. Our specialists work carefully to ensure your comfort throughout the treatment.

Most clients with thickened nails benefit from professional care every 6–8 weeks. The exact frequency depends on how quickly your nails grow and the underlying cause of the thickening.

It depends on the cause. If a fungal infection is treated successfully, the new nail growth may be normal thickness. However, if the thickening is due to ageing, repeated trauma, or permanent nail bed damage, the nail will continue to grow thick and regular professional maintenance is the best solution.

Fungal infection is one of the most common causes, but not the only one. We assess your nails during treatment and can advise whether a fungal test may be useful. If fungus is confirmed, we can recommend appropriate treatment options and refer you to a doctor if prescription medication is needed.

Yes, you can apply nail polish after treatment. However, if a fungal infection is suspected, it is better to leave the nails unpainted so they can be monitored and treated effectively. Nail polish can trap moisture and worsen fungal infections.
