Composite bonding and veneers – both options come up in conversations about cosmetic dentistry. But how much do you really know about each one? Often pitted against each other as alternatives, the truth is less straightforward and there are a few things you should take into consideration before arriving at a decision. The right treatment depends on where you’re starting from, what you’re trying to achieve and what’s really happening in your mouth (beyond the aesthetic).
Composite bonding involves applying a tooth-coloured resin directly to the surface of the tooth. It’s then shaped and hardened in single appointment. In most cases, it doesn’t require any removal of natural tooth structure which on the whole makes it largely reversible – something that matters more than people often realise when they’re focused on the end result rather than the process.
What it’s great for: Chips, small gaps, minor irregularities in shape or length, and mild discolouration that sits within a few shades of the natural tooth colour. Done well, the results can be striking.
What it doesn’t do: Significant colour change beyond a certain threshold or larger structural changes.
Lifespan is typically around five to seven years with proper care although this varies depending how the individual looks after them. Composite can chip and it’s more susceptible to staining than porcelain, this isn’t necessarily a criticism but something to be taken into consideration when making a final decision.
A veneer is a thin shell made of wither porcelain or composite and is bonded to the front surface of the tooth. It’s worth looking at the distinction between the two and understanding this before either is recommended to you.
Porcelain veneers: These require the removal of a small amount of enamel from the tooth surface. This means it’s irreversible – once the enamel is gone, the tooth will always need to be covered. It’s something to think carefully about as not everyone realises this. The positives are that porcelain offers superior aesthetics, resistance to staining and a lifespan of around 10 to 15 years with the right care. For anyone who needs significant colour or structure changes, the results are difficult to match.
Composite veneers: These involve less or virtually no tooth reduction, easier to repair if damaged and carry a lower cost. The trade off is their longevity, they sit closer to composite bonding in lifespan and there’s a limit to the aesthetic result that can be achieved compared to porcelain.
What does your current dental health look like?
Composite bonding works best on teeth that are structurally sound. If there are any underlying issues such as bite problems or gum disease, then these need to be addressed first. Cosmetic dentistry should never be used as a cover up for clinical problems.
What goal are you trying to achieve?
If it’s subtle refinement like evening out a chip, filling a gap or adding a little length to teeth, the answer points towards bonding, whereas a more significant change in colour, shape or overall smile leans towards veneers. It helps to have a specific idea of what you want to achieve rather than a general sense of something needing to improve to truly get the most out of any consultations.
What does your lifestyle look like?
Sometimes it pays to be honest. Bonding is susceptible to staining and impact, so if you’re someone who drinks a lot of coffee or red wine, or plays contact sports then it’s relevant to how long your results are likely to last.
What are you planning for long-term?
The upfront cost of composite bonding is typically lower than porcelain veneers, but over 10 or 15 years, the likelihood of repair or replacement comes creeping in. Neither option is inherently better value, it all just depends on what you want and what you’re working towards.
How do you feel about reversibility?
This is something that’s really under discussed in cosmetic dentistry conversations. For some patients the permanence of veneers isn’t a concern because their mind was made up and the results were worth it. For others, knowing that the natural tooth structure is preserved matters more to them. It’s worth considering which side of this you’re on before reaching any final decision.
Of course no treatment should ever be finalised without a proper consultation. An assessment will look at much more than just the treatment itself, taking into account the patient’s bite, gum health, tooth structure and the relationship between the teeth and the face as a whole. It’s only when the full clinical picture has been built up that treatment can be recommended for better results with fewer complications. It also tends to produce outcomes that the patient is happier with long-term because the solution has been built around their specific needs and situation rather than a general preference.
Sometimes, composite bonding and veneers are not the only treatment required. If alignment is an issue, then it might involve correcting that with something like Invisalign, first. If the foundations aren’t right, then the work on top isn’t going to cover it.
This is the part of cosmetic dentistry that tends to get downplayed when treatments are presented as ‘quick-fix’ solutions, so it’s worth spending a bit more on getting it right first time.
